As an aside, most of us here are deep into bikes and for that budget would rather get something used but that requires knowledge to do properly and of course no warranty. It is possible that someone might respond here with something in total opposition to what I have stated as opinions do vary. Sometimes you can get a really good deal on a good used bike at a bike co-op if there is one close to you. Sometimes a bike store has used bikes also. In general a purchase from a bike store, while more expensive, yields a more satisfying bicycle experience over a department store purchase. These days buying bikes at the lower cost point is difficult as there is a current buying frenzy on this variety of bike.
