Just got my Genz Benz Contour 500 115T and I'm really, really pleased. This thing sounds killer and I got it for $390 shipped. Did a Buy It Now on Monday and got it today. I can't explain the low price. I suspect it is a B stock or new return, but it came in the original box wrapped in plastic with the manual and all that stuff. It did not look like it had ever been opened. I can't find a thing wrong with it. If you are in the market you might check out this auction: Genz Benz Contour 500 115T
Mine shows a manufacture date of April 2012, but a shipping label on the box shows it was shipped from GB to the seller in August 2013. They claim to be an authorized GB dealer. Will report back if I run into any registration issues.
