Just got into this past Summer/Fall actually, got into it in kind of late in the season (those bikes are insanely expensive but you need good equipment out here).
I ended up getting a used 2011 Giant Reign 2 from Deer Valley.
Overall I love it, finally hit Moab over Halloween (awesome!!!! place kicked my ass though)
Did a few days at Deer Valley for lift served downhill as well, so fun.
Lots of trail riding around Park City, even down in SLC has some really good stuff.
Looking forward to the next season and doing some more trips.
The peak of Summmer when it's super hot here I think I am getting a lift pass for Deer Valley downhill and I'm going to get some good protection gear.
I never realized how fun MTBing could be until I moved here and finally checked it out.
