I have a 2500 upstairs sitting in the box that is maxed out!
I had it on ebay a few times, but dudes wanted me to give it away for peanuts.... Anyway, I hope I can dig into it a little bit more next month. I have messed with them both, the 2500 obviously have more bells and whistles and can do more simultaneously and on the fly than the 2000xl. The both are beasts though!
