Just bought one from Costco. 399.99 in Ontario. Model #DKC146SLDB.
Been playing around with it empty, with a glass of water on the middle shelf. Froze water the first night, about 2/3 of the dial. Notched it back about 1/16". Water (now with salt...) is at 2C (35F). Pretty much the coldest I want to go anyway as I want to have carbonated water on tap also. I'd go for 33F with beer only, as Iike my beer COLD. Looks like it would handle it without issue. Not too noisy, a bit of a fluid flow sound up close, but I figure we will forget it's there when under the bar.
The regulator is a rebranded Taprite 2 gauge. Tower and tap feel a bit cheap, and the lead warnings from California are a bit unnerving, but hey, anything will kill you in California.
Maybe I'll upgrade the tower to a 2 or 3 tap, and make a tower chiller. But for now looks like a good buy.
