Replacement range - Atwood or Suburban?

After years if struggling with our Wedgewood Visions 21" range, I've given up on ever getting the oven to heat and stay on. It heats up, then shuts off. We've tried many things including replacing the thermocouple. Before we head out for this winter, I'm getting a replacement. I could replace with another 21" Wedgewood or go with the 22" Suburban. Any pro's or con's for either brand?
I saw a good deal on a scratch-and-dent on eBay, but I'm hesitant about buying from there. Think I'll go with a new one.
