Some guy in my area is selling a gt nomad for 100 bucks. Since I'm currently riding a 10 year old walmart mountain bike, and since I'm all set to go on a one month tour in a couple weeks, I was wondering if it would be a good idea to buy this?

Do any of you have any experience with Nomads?
EDIT: just found the specs, http://www.bikepedia.com/QuickBike/B...omad&Type=bike (I think thats it)
Here are the pics:







I'll be forever in your debt if you help me out - this will be my first tour, and I don't want it to be a disaster.
Thanks alot!
