Poor man's 8-head IP-based serial console for less than $150:
As ridiculous as a USB -> 4x serial adapter looks, it's pretty boss being able to stand up a switch stack or NetApp cluster without having to move cables around. It's also FTDI.

I've test with 2 USB to serial adapters This and This. OP of the article uses This 4 to 1 cable but I personally thought it was a bit expensive.
I have the rasp pi 2. It should work with all versions though.
I haven't tested with a usb hub just yet. But I can and will. I don't see why you would need a powered one though.

I'm using this right now and it's great. The RasPi also makes for a nice little SAMBA and TFTP server, which makes it a breeze to load new images on my physical switches.
I'd recommend you just go grab a 4 port USB to serial cable and either 1/ attach rollover ('Cisco serial') cables to each of the DB9 plugs, or alternatively cut the DB9 plugs off and reterminate them into 8p8c connectors with a crimper. (You'll need a multimeter to figure out what pins go to which colours -> which colours go where in the 8p8c.)

\^ FTDI will work out of the box on both Linux and MacOS as well

That and a USB hub for devices which don't have serial ports. Which I love, because they piss off all the old fogueys running C2500s which need to die.
I use one of these.

It works quite well, especially if configured with ser2net, if you're using linux.
In my case I'm running 5 switches, on a serial port. Interfacing with Routers in GNS3 running on a Linux box.
This works great on the Pi I built for this same purpose.
