Also if you use lowes to buy the freezer use this promo code and you get 25 off
plus free shipping but i believe that free shipping is already going on.
Coincidentally I just bought one of these from a Craigslist ad for $60 last Tuesday the 23rd. The original Lowes receipt was included with the paperwork and it had originally been purchased at the end of January 2013 for $180, so score!
I spent about $10 and built a 2"x8" collar which I lined with some 1" Dow insulation sheeting I had left over from my keezer build and so far it has been rock steady holding two buckets of a Blue Moon clone at 68-69 degrees (in a room where the average temp is probably in the mid 80s) using my old Johnson Controls A19 electromechanical temp controller. I spend $20 at Lowes and bought an indoor/outdoor thermometer with a remote sensor I keep in the freezer and I also added a small computer fan.
I put my Kill-A-Watt EZ energy monitor on the whole package and after running it about a week at 68-69 my yearly energy expenditure is estimated at $6.83. I didn't even permanently attach the bottom of the collar to the freezer, it just rests right on top of it, because I have the freezer tucked away in a corner of my storage room and without the collar permanently attached, it is much easier to get the whole top part out of the way to add or remove items from it.
