those are the bike your interested in. but it is the 1999 model as seen here
now lets say your buying a used 10 year old 4x4 truck that has most likely been used and abused its entire life how long to you think the shocks/tires/transmission/engine will last. not to mention that over the last 10 years bike design has improved significantly making that model basically obsolete.
also do you know what size bike you need? a small frame will not fit someone from 5' to 6'. its just not made to do that. well not comfortably anyway.
entry level bikes are a great way to start. they let you get the feel of the bike and let you determine the riding style and what you want out of a bike without spending a whole lot of money.
the best advice i can give you is to go to all of your LBS (local bike shops) and test fit as many bikes as you can, then look through CL for what you want, or buy from the LBS. they usually give you discounts of the items your gonna need for your bike if you buy from them. like a HELMET, seriously you need a GOOD helmet, bike pump, tubes, whatever....they also usually throw in a free year of tune ups...which for someone just starting out not knowing much about bikes is always a good thing. since most times they charge ~$40 a tune up.
thats my $0.02.
