The biggest cost is the receiver. It is the heart of the M1A and you can just make them cheaply. A good receiver will last a lifetime and shoot thousands of rounds and stay in spec. The iron sights are military type peep sights and are good for man sized targets within combat ranges and target shooting within reasonable ranges. I have a Super Match from 89', a Loaded with NM bbl and sights from 97' and a Scout. I've never had a FTF or FTE with any of them and whenever I go shoot people ask me about them. There are some nice 7.62mm battle rifles out there but to me nothing beats the feel of steel and wood and the M14/M1A is the battle rifle of choice. It's sorta like the 1911 in a way, every time people claim it's dead it comes back to center ring. IMHO YMMV
