Ahh. Gotcha. I didn't realize they had a gas powered one. That would be nice! I didn't see it at the HNA show and the sales guy who stopped in Portland one day never told me they had one either. But that would eliminate two of the problems.
If the gas one stays on all the time (e.g. no trigger) - or if the engine at least doesn't turn off every time you take your hand off the trigger, then this may be the ideal machine. I wish I would have bought that one!
