Cooling Units

[MontereyRick]

I bought a home a couple of months ago with a wine cellar in it. Sizewise, it is awesome. It is right off of the kitchen with a private door and a set of stairs that drops right down into a cellar approximately 15'x 11' x 7'ceilings. <P>It has beautiful redwood racking and diagonal bins to hold around 500 bottles. We are in the process of faux painting the walls and putting slate on the floors.<P>While it is definitely cooler down there year round than upstairs and is completely dark, I fear that the temperature fluctuations could still be harmful as I am interested in cellaring some wines for many years.<P>I need to install a very nice cooling unit and don't know which one to buy. Can anyone give me some advice as to wine-mate or breezaire or any others to focus on or avoid? Any tips or special things to consider would be greatly appreciated.
