I wouldn't be opposed to spending ~$1500 on a brand new QUALITY M1 Garand that I can shoot and modify without worrying about it's historic or collectible value, maybe even a bit more. The problem is, I don't have that kind of money and even if I did scrape it together I probably wouldn't spend it on one gun.
Then get a CMP Garand. Maybe a Special Grade. They are, for all practical purposes, a new rifle built on a refurbished receiver. $995. The CMP doesn't have an "official" warranty, but if you have any problems, they WILL take care of you. Their CS is the best around.
Or do what I did and get a Service Grade for $625. Mine can with a 1954 rebarrel that looks like it has never been shot.
