I've been using the Behringer P2 for a couple of months and love it. Doesn't pull your pants down like the heavy P1, and as EBS Freak rightly said, the P2 has a built in headphone amp unlike the P1M. Gigged with it a few weeks ago and it works really well. Big thumbs up from me as a noob to IEM. And I can happily use it whilst I save up for a wireless system.
