Second-hand shops and thrift stores in Stuttgart

Hello! I have been here in Stuttgart only a short time. I am looking for thrift stores or second hand shops that sell kitchen items on euro voltage. Also, I would like to find a place that also has transformers that are used. Any advice is appreciated.

You could try Caritas Fairkauf (http://www.caritas-stuttgart.de/17358.html)
They sell 2nd hand stuff @ a VERY reasonable price. Not too sure about the quality of appliances you get there though..
