There are two Danby Kegerator models available. The smaller of the models is DKC146SLDB coming in at 5.2 cu. ft. Danby model DKC645BLS is larger at 5.8 cu. ft. and has a few additional features. Both are moderately priced and have good reviews online.
This kegerator is Danby's entry level model. It is black in color with a stainless steel looking door (not real stainless) and a black or chrome beer tower.
If you shop around, this kegerator can be had for under $600 delivered.
This is Danby's higher end kegerator. It too is black in color but has a real stainless steel door. The beer tower in comes black or chrome. This kegerator also has an electronic temperature control opposed to mechanical temperature control as used in the DKC146SLDB model.
This kegerator is a little more but is still under $650 delivered at some stores.
Both Danby Kegerators are similar in features but the DKC645BLS is definitely a little better and worth the few extra bucks. You'll get more room, real stainless steel door and an easy to use electronic control and display.
