I just (this week) received a service grade Garand from CMP. It is a May '45 Springfield, with its original June '45 barrel. Muzzle erosion is "1", throat is "3". Has brand new walnut stock and hand guards, and is in about 98% condition. Price was $730 shipped.
As for rusty, cracked, corroded, worn out Garands being overpriced, I would invite you to read my first paragraph again. This rifle's market value, right now, is about $1,000. I would not sell it for that price. I plan on a long love affair with it.
And, if I can get a 1911A1 from CMP for $1,000 in similar condition, I'll stand in line all day! Colt WWII 1911A1 pistols in nice shape are bringing upwards of $2,000 now. I wouldn't mind adding another one to my collection.
