Definitely fun and great value for a recent release. The Demon spitting SDTM can be eliminated by adjusting the mechanism. That is really the only common issue on the pro. The art is great, the sound quality is great, it shoots quick and clean and the lighting is impressive (even on the pro). The ruleset while better than than the common perception is still not the highlight. Hopefully the update coming this summer will clear the remaining bugs and add a few improvements. The pro is the way to go, IMHO. You won't miss the Prem/LE extras nor the additional mech maintenance.
The fact that you enjoy playing it on location seems like a no brainier decision.
