Gbnk82, if you are in Florida (I am too) you should be able to find an M&P15 Sport for $839 locally.
I just bought one myself at Shoot Straight for that price. the M&P Sport is an excellent rifle for the price. I have not had any problems with mine after shooting hundreds of rounds. I runs just as good as my other AR15's (Spike's, Bushmaster's, and PSA's)
Do not let the lack of FA and dust cover bother you. Its not a deal-breaker by any means. An AR15 will run just fine without them; of course they are nice to have, but Smith and Wesson didn't add them on the Sport as a cost-cutting method. Nevertheless it does not affect the rifles reliability.
