Kimberly:
I dont know how big/small you are, but my girlfriend (5'2 105LBS) tried the trek "womens" spec bikes and they didn't fit her at all (hurt her knees when she pedaled even with it adjusted "properly" she just didn't like it)
Then we went to the bike store I deal exclusively with (they have kona and bianchi...what more do you need...ok colnago for road maybe but they are a store that has my price range and then some)
Anyway my point is I ended up getting her a Kona Blast. Now I know that bike is a little higher then the ones your mentioning but I think you might like the low end Konas
Just something to consider (PS I have a Kona as well and we both love our bikes!)
