Wine Storage Experiences/Advice
 

First, thanks in advance to any an all for offering their experiences/advice
on home wine storage. I finally have space, about 100 square feet, where I
can set up a racking system and ideally a "cellar-unit" too for temperature
and humidity control. My "small" collection is about 200 bottles at the
moment; probably half of which need or wouldn't be harmed from some extra
time to develop.
What cellar-units have you used or encountered; good and bad? While a
decorative or a furniture-esque finish is not important to me, a good value
is important. Self assembly is not a problem. Any cellar-unit suggestions
would need to accommodate champagne bottles and a few 1.5L bottles. If
local matters, I'm in the southeast USA. Thanks again.
