Hello and welcome to the forums. I sugest that you buy a bike from you lbs. The 50 -70 that you save is not worth it, because unless you really know how to put together a bike you will just spend that much at you lbs to have them put it all together.

Most of the time you will find that a bike shipped from a onlin store will have problems that the product gets damaged when shipped (bad fedex driver lol

I say just get it from a lbs, there you will get much better help and most of the time they will give you free tune-up for some thing like 90 days (that in its self will be worth the extra money if you ride a lot)

Hope this helps some and feel free to post a lot here!
