The CK flex-loc is a nice torch, but I'd recommend learning on a simple rigid -17 just because it's almost universally familiar to everyone in the industry and it's what almost every welding school will start you off with. The reasoning is that a -17 is basically the industry standard torch for most work under 150 amps and it's a torch you'll come across it almost everywhere. A rigid -17 will do for 95% of what you'll be welding, it's cheap, it's reliable, and almost every welding supply will have parts for it if you need anything. What more can I say,? This is a no-brainer decision unless you will be doing stricly low amp work (if so, a -9 might be prefereable). I'd save the CK flexloc for a little while later when you want to get fancy, stick with the basics for now.

My recommended "basic essentials" shopping list:

• CK-17 with the super-flex hose (Radnor power cable hoses aren't particulary nice, CK superflex hose is way mo' better)
  
• Torch connector to fit your particular machine
  
• 10 pack of 3/32" 2% lanthanated tungsens
  

• 6 Stubby gas lens (at least 1)
  

• 6,7,8 cups (at least one of each)
  

• 3/32 collet body (make sure you get the right type)
  
• 3/32 CK wedge style collets. (the CK wedge style work a LOT better than split type collets)
  
• Assorted back caps for torch (one button, one shorty, one long)
  
  A lot of this stuff your local welding supply should carry or you can get it on Ebay for cheap. -17 torch parts are pretty generic. On the subject of welding supply stores, I would NOT recommend Airgas unless you like paying full retail + 25% price for everything.
  
  You will also need a cylinder of Argon (80 cubic foot is a good size for a hobbyist), a decent Argon flowmeter, and 6' of inert gas hose (Argon uses 5/8-18 "B" fittings) if you want to be able to use your new toy.
  
  I'd also recommend two 20' lengths of #2 or #4 gauge cable for you ground and stinger leads (TIG will use the same ground cable). For a stinger the Lenco 200 amp is pretty much industry standard for light duty. For a ground clamp, buy the nicest one you can afford -- Nothing pisses me off more than a shitty ground clamp - it's a pet peeve of mine. ("Earth" clamp for the Brits here, and "Work Lead" for the technical nitpickers)
  
  Keep in mind that aside from the specific machine connectors which are only really useful for your specific machine, almost everything else I mention you would have to buy with any TIG welder. Welcome to the club, prepare to be "nickel and dimed" for a while until you settle on what works best for you.
