You can build an AR-15 yourself for under 750 easily and even get it down into the 600's. Its all dependent on what you want to do. I'm partial to the AR-15, but at the end of the day its up to you to define what feels good to you (ergonimics and so on).
First thing I would do is go handle both firearms at the store, because both feel quite different. Second I'd determine what I plan on doing with it (competitions?, just plinking?)
If you get an AR-15, the style you choose will soley be dependent on the purpose of the rifle. IE, you dont want to get an AR-15 carbine thats bone stock for competitions. If its just a throw around plinker you can easily build an AR-15 in the mid to upper 600's that will be quite reliable and accurate.
