I like the Del-ton idea as well I have heard good things about them. I believe they were $750 with some goodies included. Also remember with those online deals you have to pay shipping and a transfer fee which could easily come out to $50.
If you were interested in building a budget AR you could also pick out a lower receiver locally and then pickup a rifle "kit" from many reputable manufacturers that includes everything you need to build the rifle shipped to your door (except for the lower receiver which needs to be transferred through an FFL dealer)
here are the del-ton kits

Rock river arms is a highly regarded manufacturer and this kit has a 2 stage trigger:
