If you have the space there are under-counter "beverage centers", which could be used for both wine and other beverages, like beer and pop and such. This would give you the option of freeing up room in your main fridge and giving you other options in choices for a fridge.

I am not familiar with other options off hand for a fridge that has that as a feature.

You could try a site like AJMadison.com and see if you can refine a search on there for something like that to see if there are other options.

Elux also has a drawer that you can use for wine storage.
If you get the perfect temp drawer - you can adjust based on what you put in the drawer :-)
