Technically, it's the wrong forum. Happens all the time, though.
I think it's supposed to go in Miscellaneous. Just PM a mod, and they'll move it.
Anyhow, about your question... I've been meaning to try out an X2 to see for myself. GC carries them now.
I really do think that, based on what I've read around here about the X2, that the old X-Wire is beaten on all counts. You're going to have a hard time getting a decent amount for it, IMO.
