I think the new Springfield Armory Garands cost more than original Garands. You can find originals in gun shops for around $700. on up depending on how original they are and their condition.
Mine is a 1943. It's a Springfield, the most prolific manufacturer of Garands. At the ages you'll find one, it's highly unlikely that you'll find one that's all original and matching. Most have been rearsenalled over the years and whatever parts were necessary were changed out with the parts on hand. That's where the term "Mixmaster" comes from.
All original and matching will cost appropriately. Generally they can run from $1500. on up to crazy money.
I will say this....
there is nothing else like a real Garand out there.
