In Oregon, I picked up a stripped RRA lower ($120), DPMS lower parts kit ($55), buffer tube, buffer and spring ($45), and magpul moe stock set ($65). Thats a total of $285. The assembled lowers I saw on the walls of the stores and shops i visited while bargain hunting were averaging $300-$400. So its not a huge savings, but I personally like that I know where every stupid dissapearing piece and "shoot across the room for no reason" spring and pin is, and how it got there. I had to buy a case of beer for my buddy, who found one of those little brass brads that go in the pivot pins, after it decided it didnt like its position in the universe, and made the choice to make a random E&E from the receiver, to someplace on the carpet 20+ feet away.
