I like Spikes Tactical in Apopka, Fl.
I'm not a weapons expert by any means, but I've seen a few others on the board here give spikes their approval in terms of product quality.
I can however vouch for the experience in dealing with them. Great professional people that were very receptive to my questions and very hospitable. Ask for A.J. if you give them a call.
I got their standard M4 with the 14.5" 1:7.
Great tee-shirts too.
