Went to a LBS today and he had the 3900 for around $500.00.It rode really good and I believe it would be ok for my first bike.The guy was really nice and knew what he was talking about.He even told me that I would need a 19/19.5 inch for my size.I believe I appreciated the fact that I was a beginner and he answered all my question(even though some may have been dumb) and didn't make me feel like I was wasting his time.So should I jump on it? I will be headed to a few more LBS when I go on a trip next week that have Trek,Giant and Specialized and can do special orders as well.Should I wait and see what they have?Thing is with them they would be a 45 min drive if I needed their help with something.I'm sure the other shop would help,but would charge since I didn't purchase from him.I was looking into a 29er,but I believe a 26 would be fine.
