Thanks for starting this topic. I am more or less in the same situation -- small apartment, wine collection has blossomed from 10 to about 35 bottles in the last 6 months. About 5 of those probably need 1-3 years to mature, but I am sure that number will only grow.
Until now the "drink now" bottles have been in the living room in a wine rack/bar, and the others in a cardboard box in the bottom of the most isolated (form temp. changes) closet in the apartment.
Thanks to all of the advice here, I too am considering the Edgestar 28 bottle cooler. I would only keep reds for long periods, and if I got over 28 bottles I would seriously look at an off-site solution, so I think this should do for now. I am very interested to hear any follow-ups you have (or anyone else has) on the quality of this cooler.
Thanks again to all.
