Definitely go play them - both the Schecter Omen and Jackson JS series have good guitars and bad guitars - build quality is all over the map with those. I went through 3 JS32-7s to get the one I kept, and 4 JS22-7s. You'd think there was hundreds of dollars of difference between the best and worst I tried, but they were the exact same models.
Twin JS32-7s, big difference in build quality.
2 different JS22-7s, one had soapbar pickups, one didn't... but same exact model (??) build quality on the soapbar one sucked - total dead plank. Then, I got another standard pickup one that blew both of these away and it became this:
I wouldn't have any issues playing this on stage - don't know that I'd tour with it unless I got the frets cleaned up a bit - but for a guitar I have less than $500 in, it's pretty sweet.
So, as a beginner, I'd say get a Jackson - you can mod it as you grow and learn what you like and don't like (change pickups, tuners, bridge, etc.) and then eventually get yourself a more pro-quality one like an X series or Pro Series.
