thanks for all the responses so far, will have to spend some more time looking obviously. just wanted to clarify some of my requirements that i didn't think to add in my OP.
i have a medium sized NYC apartment, so i don't have room for a huge one. 50-60 bottles is about as big as i want to go.
i semi-frequently buy $50-$100 bottles of wine, but do not intend on buying wine in order to age it myself. i like to order some of the nicer stuff from
www.winestillsoldout.com and/or pick something up every month or so from the wine store on my way home.
