Which one???

Okay I need some help. I'm going to buy a bicycle...yep a bicycle. I'm out of the 4-wheeling business! There is so much to know about bicycles! I had no idea. Suspensions, forks, brakes, grips, saddles, frames... I have narrowed it down to three bikes; all are aluminum frame and one of them has disk brakes, which is supposed to be better than pad brakes. Here are pictures of the three I'm looking at. They are all similarly priced...but I just can't decide. Which one do you think I should go with?? Or if you know someone that knows anything about bikes, ask them for me! Thanks!

Jamis Durango with disk brakes

Giant Boulder with pad brakes

Specialized Globe Carmel

Update!

Okay, so, it's been a few weeks since my last post. Here's a few updates: I'm finally going to get into the duplex about mid-April. I'm sooooooooo excited! Not that I haven't enjoyed the free rent at my sisters place, it will just be so nice to have all of my things out of storage and stop feeling like I'm living in a suitcase. My eye's have healed wonderfully! This is truely amazing to have such great vision! For those of you that don't have any vision issues...you are blessed. For those of you who know what I went through for the majority of my life, not being able to see 10 feet in front of you without glasses or contacts...I HIGHLY recommend getting lasik! Any questions call me! The weather has warmed up so quickly. Sadie is shedding so badly, it's hard to believe that she still has any fur left. I tried to get her into the groomer and they're two weeks out! Spring is here!!! :)
