I'm hopeing everyone might be able to help with this. I've been out looking for a mountain bike to buy and have come across some real goo bikes. This will be my first mountain bike so I'm looking at more entry level equipment. One bike that I found was A bike by The North Face. I can't find any info on it and am unable to figure out who makes the bike. It has pretty good components, but I still like to find out who acctualy makes the bike. Any Ideas.

Also mabety give me your opinionb on some of these bikes

Trek 4300
Specialized Hardrock
Schwinn Mesa GS
Iron Horse warior sport
The North Face Pompeii

Any info would be great, Thanks!
