There is a huge thread regarding the Edgestar 'fridges around here somewhere. I've had mine for 3-4 years now. It is used 24/7 in the house as a beer/soft drink cooler. It has seen countless off road trips, rattled around, beat up etc. Mine has held up well. I had to replace the lighter socket end of the 12v cord (solder broke on one of the wire connectors, easier to replace the whole plug than it was to fix the solder when/where I figured it out), other than that mine has been trouble free.
I got mine through compactappliance.com, they have a scratch and dent section that has some smoking deals time to time.
