12 bottle vinotemp - any point?

[BigCat]

I see that ebay is littered with 12 bottle thermoelectric vinotemps for $50. I was curious if anyone is familiar with the box capacity of these. I am interested in getting the 28 bottle model that everyone seems to rave about, but my wife and I are getting ready to move and I can't justify the $400 price tag on the bigger ones at the moment. The weather is getting warm around here though and I also can't justify running the two wall unit air conditioners all day while we are gone to protect my sticks. I have a 50 qt cooler right now with about 10 boxes in it of varying sizes. Are these likely to fit in the 12 bottle? I guess I am just looking for short term cheap protection.
