My favorite (inexpensive) burr grinders are a Cozyna portable and a Hario Skerton.

I have this one have used for 1 year now.

To answer your question, the strength of your coffee is mostly influenced by how much coffee you're using versus how much water. For a strong cup with your Keurig, go with the setting with the smallest amount of water. The Keurig is by no means the "best" method to make coffee, but it will make coffee. If you decide to get a manual brewer (French press, Aeropress, Kalita Wave, etc.) the brew time has some leeway, but I'd recommend just using more coffee than trying to push the recommended brew time too far. Coffee can/should be strong without being bitter, and keeping the water and coffee together too long will create bitterness.


What follows is everything you need to know about making great coffee. Warning, this may be overwhelming:

1. Freshly ground coffee is going to taste better. Consider coffee like bread. A loaf left on the counter will get stale faster if you slice it up. Freshly roasted is better, but it might be more expensive/harder for you to find and you might not want to dive that deep yet.
   
2. Conical burr grinders are better than blade grinders. The problem is that a decent automatic burr grinder is going to be ~$100 and that's a steep price for someone just getting into coffee. Many people will recommend the mini mill, Skerton, or something along those lines that is hand-crank. (Good non-name brand options: 1 and 2) Those are your best bet. Although I wouldn't necessarily recommend it, you can get an automatic blade grinder if you might have an issue with manual grinding/don't want to drop a lot of money. I will mention that darker roasts are easier to grind manually so there's less worry for your wrist. The problem with blade grinders is you get a bunch of differently sized bits, which makes it more difficult to get consistency and figure out a grind size/brew time you like.
   
3. Each method of brewing calls for a differently sized grind. This is pretty important. If it's too small, you'll get a bitter cup. If it's too big, you'll get a sour cup. The same goes for brew time. Too long will make a bitter cup, and too short will make a sour cup. However, there's some leeway on both of these to your taste.
   
4. There are a bunch of ways to make coffee that change how it tastes. Methods that involve filtering through paper make a cleaner cup, but you lose most of the oils in the coffee. Metal filters leave in these oils, but can also leave a lot of sediment/mud in the bottom of your cup. You might drink this if you drink that last sip, and it isn't really nice.
   
5. Weighing your coffee is much more accurate if you want to make a consistent cup. A tablespoon of a darker roast might be 5 grams while a tablespoon of a lighter roast might be 7 grams.
   
6. You'll need something to boil water in. If you have a kettle, great. If you don't, you can use a pan or you can buy a kettle. It doesn't need to be a fancy/expensive gooseneck-style one (1 and 2), but you might want one of those if you get into pourover methods.
   
   I would recommend a French press (1 2 3 4) or Aeropress for someone just getting into coffee. They're much more forgiving than pour-over methods, meaning you're less likely to make a bitter cup. They each have their own drawbacks, too. An Aeropress is easier to clean up, but can only make one cup at a time. A French press takes more time to clean, but can make about 3 cups at a time. (By cups I mean a standard 12-ounce mug.) Definitely get a grinder, too (see above). A scale (1 and 2) is optional but recommended. For beans, seek out a local roaster/coffee shop, but there are tons of online options available, too.
   
   Welcome to the wonderful (and sometimes crazy) world of coffee!

This manual one by Cozyna is on Amazon for $20:

I've been using it at work for the past month or so and it's great. Very minimalist design but very well put together. I use it for Aeropress coffee so the grinding goes pretty fast, not sure how it compares in terms of speed to more expensive models.

I picked up this one a while back for camping, and it worked really well. It slides into the Aeropress tube for easy packing.

Although it looks like that model might be discontinued now, there does appear to be many other grinders that use the same shape like this one but I cannot speak for it firsthand.
