I purchased a once used XL BGE at the Southern California Eggfest last year. It's worked for me great so far.
The company that sponsors it is here: http://outdoorkitchencreations.net/
Unfortunately, they already sold out of the once used eggs for this year's Eggfest. However, these people are really great. Great service, answer all questions, etc. If you go to the Eggfest, they'll probably have a regional representative there to answer any more questions.
However, as I've explained before, I don't think the BGE platesetter is great in my experience. Maybe it's how I"m using it, but I don't feel that I get enough circulation or smoke when I use it. I'm seriously considering buying the indirect setup from this company: http://www.ceramicgrillstore.com/
Feel free to message me if you have any questions.
lus1: I am starting to feel the same way.
