Which of these is good for an entry-level women's mountain bike?

I am looking to purchase an entry-level mountain bike, with a price limit of about $800. I have done my research online and have narrowed it down to a Trek 6500 wsd or 4500 wsd, the Specialized Myka Elite, or Gary Fisher Marlin GS. I haven't had a chance yet to ride any of these, but I just wanted to see if anyone has an opinion one way or the other about which might be a better value for the money with the components that come with the bike. I also looked into the Kona Cinder Cone, but I'm not sure that I'll be able to find one near me. Thanks!
