Isaac, you can try G&R Tactical, for both uppers and lowers. They have LMT Defenders w/SOPMOD & two stage triggers for $511. He often has items in stock that the website doesn't reflect. There are three nice complete rifles on the front page right now.
Again, if you've got the $, I doubt you'd regret the Noveske. If you have money to burn, check out the new FDE SPR on Noveske's main page. Absolute 18" Nirvana.
