Lot's of good responses! Thanks for all the input! I make a lot of custom door's of all sorts: Screen doors, french door's, exterior gates, carriage, etc..., as well as built ins, etc... Therefore it would make sense to own the XL. The only reason I ask the question is, I'm not sure I can swallow spending $1200 on another domino at this time. Obviously if I sold the 500 it would greatly help to fund a tool that I most likely would use more than my current domino, but at the same time don't want to regret it in the end. I think I will purchase the XL and from there get a sense if I need both or if one will do. In the end, I'm guessing I'll need to find a new spot in my trailer for another domino
