Yeah, price is the main determining factor. I see that it's a 1 tap tower in the pic. If you're up for DIY, you can get a Sanyo fridge and 2 tap tower off of e-bay for under $500. With this, I'd make sure it's the correct connections for whatever keg system you're going to get into. It could be this system is for a commercial keg rental...which is not compatible with the usual corny kegs that homebrewers use.
On Tap: Barleywine, Coffee Oatmeal Imperial Stout (big big beer)
Fermenting: Double Simcoe IPA
