My only experience is with smaller countertop wine coolers, but one I used did manage to keep about a 10°F difference between the topmost and bottommost shelves. Not divided into neat zones though; the middle shelves are simply between the two temperatures, the lower the colder. I've never found the standard temperature rules for red/pink/white wine to necessarily be the best though, with for example, shiraz tasting better when served cooler than cabernet even though they're both red, so the variable temperatures proved useful. Some wine coolers work like most refrigerators - they use a compressor. Others don't use a compressor, which have the side benefits of being silent and making more efficient use of space. Both varieties can be made to cool different compartments to different temperatures if designed carefully. You may want to crosspost this question on the GW wine forum too.

I'm starting to do my research and it seems like the $700 fridge has good reviews, but some people were posting about the noise. We are usually watching tv or cooking and I didn't think a little noise would be a problem.

Marvel 24" beverage cooler SS surround- plenty big for the 5 of us. But definitely the LOUDEST appliance in my kitchen!!! Here is a link that might be useful: Marvel in my kitchen

You could always choose a refrigeration drawer with a storage drawer below it.
