with some scrounging around you can get a cheaper keg set up than what you've posted.
2 – five gallon ball lock refurbished kegs. (20 bucks each)
1 - Brand new 5 pound CO2 cylinder (most of us guys have an extra laying around you could pick up on the cheap maybe 30 bucks or so - who cares if it's not brand new)
1 – 2 Keg CO2 kit (2 way valves - disconnects - tubing - accessories: $100)
1 - Dual Tap, all metal, Chrome Draft or Homebrew Beer Tower kit (i've seen ppl make these and they look awesome - two faucets $15 each - no they're not perlicks - some pvc - come pvc paint a little time - bingo)
1 - Brand New TapRite dual gauge CO2 regulator: (refurb'd one will run you $20 local)
also keep an eye out in the free section of craigs list greenville, and freecycle greenville - i see those type fridges going sometimes - and a plethora of chest freezers for free or cheap
