I am relatively new to Gas Gas. I have been quite pleased with my bike though, the motor is just fantastic and the bike just feels light and flickable like my yz125. But it has that awesome tractor powerband if you need it. Couldn't be happier.
I really hope Gas Gas continues its success, if they could get to the point where Husqvarna is that would be great. Even Husaberg seems to really be exploding these past two years.
Side note I'm up in Seattle right now visiting my grandparents and went into Tasky's Metric Cycle in Everett. Very cool shop and awesome staff, had quite a few Husaberg's and Husqvarna's maybe 15-20 or so plus like 8 used bikes. Looked like they stocked quite a few odds and end for them based on what I saw on the wall. I was a little disappointed not to see a single Gas Gas though. I should have asked about it. I did tell the lady helping me I rode a Gas Gas though and heard about the shop on the forums.
