An alternative worth consideration is to buy a Springfield Armory receiver and a USGI parts kit and have a competent gunsmith put it together for you.
I've got a M1A that was assembled by Ted Brown, a noted M1A 'smith. It's all USGI Winchester parts on a Springfield Armory receiver. There are NO National Match parts on the rifle, but it will shoot sub-MOA with Federal Gold Medal 168gr. Match ammo.
I don't know what it cost for the parts & labor that went into this rifle, I traded for it earlier this year from the original owner. I've seen similar rifles built by Ted for $1200 on the internet.
FWIW- Ted Brown works out of an establishment called "The Shooter's Den" somewhere in Oregon. He was an Armorer in the Marine Corps at one time, so he knows all the "tricks" to build a quality rifle.
Ron Smith of Smith Enterprise in Tempe, AZ also warrants consideration.(

Both, however, are likely to have a waiting list.
