A 10' x 12' Restaurant Cooler for $3,700
A Restaurant in Maine built one of the tightest coolers I've ever seen. Materials for the walk in were about $3,000, the AC was $400, and of course the CoolBot is $299. It's a terrific write-up! Plenty of people have hacked together cheaper coolers (including me) but these folks really didn't waste a dime. It's all in better materials and wall finishes that many people skip in non-restaurant coolers. It's outstanding!
