SA only made a limited run of M1 Garands from 2001-2002. And the productions numbers were around 1700 rifles. They have the information on their web page still so you can download the manual. Your best bet on buying an M1 Garand is when the gun show comes to your town. Many are in pristine condition but they aren't cheap. Expect to pay around $1500 for a perfect specimen. Parts are plentiful seeing as they were the second most produced battle rifle in WW2.
