So I am an avid thrift store shopper and I have bought a great deal of kitchen appliances and such. The last great buy was the George Foreman G5 grill with interchangable grill plate, everything included for $20. I have gotten a great deal of Le Creuset and Descoware enameled cast iron for virtually nothing as well.
My latest thing was not something I was actually looking for but rather something I came across quite by accident. It's the George Foreman mini roaster GV5. Here it is on Amazon: Amazon.com: George Foreman GV5 Contact Cooker: Home & Garden
I didn't know what it was when I first saw it but it was brand new (not in a box) and so I went home and looked it up on Amazon. The reviews are fantastic but the device is no longer made. I ran back to the thrift store and bought it for $8. I have just made a roast chicken in it and it's awesome!!! We are only a family of three and we don't require huge meals so this little device is perfect. I try not to heat up my kitchen in the summer by using my oven so I think this is going to work out great.
My holy grail of thrift store shopping is going to be a Vita Mix. I doubt I will ever find one but I am always hoping.
