I should add that I'm talking about undercounter appliances in both cases. The only combo full size units I've seen (which we could put in the butler's pantry / wet bar) are very expensive. Thx!

Positano, when ours was new, I could here the relay click (it was honestly more like a twang) when it cycled on, but it was quite quiet while on. The service guy guy came and checked it out because I was concerned the twang was some fan parcially stuck. He explained that it was the type of relay they used, and that after a while it would be quieter. He was right; know we don't ever notice the relay, except if I have my nose in the fridge looking for something when it kicks on.

Got mine at Home Depot. It was a Magic Chef, they still have it in the stores (but I don't see it online) but the name has changed. They also offer a wine fridge model but the one I got has glass shelves not wire shelves for wine bottles. I spent $300 (on sale) I saw them recently for more $$; sorry I forget how much. It is Stainless steel, has a glass door and looks great. The down side is that it only gets down to 39 degrees, which we are okay with, but it sounds like you are looking for something that will cool them down much more. That said, a quick bout in the freezer would do the trick, so I guess it depends on what you are willing to spend!

I just bought a factory seconds from Perlick but it is the "C-Series" and it is louder than their Signature Series, just keep that in mind. For my wife and I who are upgrading from a free standing unit that is almost 15 years old from Sam's Club, the sound is just about the same as that old unit.
