I bought 2 PSA lowers in 2011 for 49.99 each. PSA makes a very good lower, but by the time you pay shipping and FFL fees, 99.99 is just an average deal. At least it was prior to 11/6/12.
PSA has some complete rifles in you price range, check 'em out.
1 to 7, 1 to 8, 1 to 9, are all good general use twist rates. The faster twist rates handle heavier bullets better.
