That is a great find as is if you use a 50L sankey. If you want to retrofit it with a new dual tower, corny fittings with the sankey, regulator, tank, etc, then you're paying $300 for a fridge with a sankey coupler.
I'd suggest you really think about what you want your final setup to be. If you want 2 kegs and a dual tower tap, costco has a stainless mini fridge that will hold 2 corny's when you take the door plastic out and a 5lb CO2 for $159.
Brand new with warranty, just saying.
Now, if you want 2 kegs on tap and 2 kegs nice and cold to swap out, then you might want to go for the kijiji fridge.
