Welcome Dave,
I haven't heard any other reports of the XL1500 either. I think it may be that most serious Airgunners will shy away from guns with that much speed because of pellet instability breaking the sound barrier. Plus, so far, the guys who've been buying them are using them for larger game, longer range hunting and the 22 has the edge there.

How about giving us a review of yours? What pellets are you using, and what speeds are they giving - what hold works best for you - how loud is it and what do like/dislike about it, etc
?
Paul.
