I picked up a similar Chest Freezer on Craiglist. A 7.0 cu. ft. that was much cheaper than anything else out there. I had to troll for a month & pick it up immediately or else it would have been gone.
The internal thermostat didn't work for me either. Tried everything over a period of 1 week. Screwing it in, screwing it out. Trying different screws. Nothing worked. The brand is an Estate by Whirlpool & search found me nothing. The was built in '96 but works like a champ. I hated to do it but I picked up a Johnson A19 last week. I've spent too much time & $$$ building a collar to break it & start over. Home Depot alone I spent $90 on supplies.
The actual kegging equipment is where the real $$$$ is spent. There was some fella selling a home made kegorator with 2 taps, kegs, CO2 & all lines for $175 but it was kinda thrashed. It worked but it wasn't all clean & nice........... and I didn't grab it. I'm kicking myself now!!!!
A black insulating strip replacement cost $78. I wasn't going to do that! Since I let my 10 year old daughter go nuts with the chalk, I'm glad I didn't.
