I picked up a wine fridge the other day, it's a Kmart jobbie, and cost me $199 (stocktake special) it claims to hold 40 bottles (I reckon it'll be a bit squeezy by 40) and has digital temperature control from 7 degrees to 18 degrees, with a digital LED display so that you can check the temperature easily.

Compared to the other "budget" options (Target have a 24 bottle jobbie with a dial from "warm" to "cool" for $249) it certainly seems like a good deal, not sure how they stack up to the Vintec and other higher end options though.
