Norinco NP22. Rumoured to be a fairly decent copy for the price. SFRC and other supporting vendors above would be the first places I'd check.
AR-15s are awesome fun. Norinco has one around the $600-700 price range, but for a bit more, you can work out NEA or Aero Precision, and a bit more than that you're into some really good quality rifles. SFRC, Questar, OneShot, and many other vendors above.
Lots of shorties to choose from, but Remington 870 and Mossberg 590A1 are two top, affordable pumps. (Also look at Grizzly).
