o.k. I don't own and havn't run either of these speedo's so therefore have no personal experience of either. MTronics have had an extremely poor reliability record in the past (if it blew up, it was probably MTronic...) and I've only heard good things about their customer service (sounds like they had alot of experience to get it right)
However, everyone that I've spoken to who runs MTronics these days (admittedly most are sponsored by them in some way) say that the new IP6 is 100% reliable and a superb unit as well.
Still, I'm gonna buy LRP next
