Critter,
I HIGHLY recommend spending some time at
www.jouster.com and
www.battlerifles.com. Jouster (Culver's Shooting Page) has a very informed group of Garand adicts.
I would shy away from a commercial Garand - there have been many reports of just junky parts on them including the receiver being cast and not forged.
You can find a WWII or post war Garand at many local shops in the $800 range. Right now the hot ticket seems to be the 6M range Springfields as they represent the last of the "real" Garands and are in almost new condition.
Don't overlook a WWII Garand - I love both of mine.
Garands were built by four vendors for the Goverment.
1 - Springfield built the most and is the "creator" of the rifle.
2 - Winchester built only during WWII and while their colectability is high, their workmanship can leave something to be desired.
3 - H&R built Korea and post war Garands are are highly regarded
4 - IHC (International - yes the tractor people) also built Korea and post war Garands and are collectable due to their small production numbers.
"Danish" Garands are highly regarded as well. Our government loaned the Danes a bunch of Garands and the Danes did a fine job of reconditioning them with top quality parts and some of the best barrels (the Dane VAR barrel).
Personally - I'd start with a WWII Springfield. You are getting a piece of history and a rifle that if it's been through the armory program and fitted with a newer barrel will shoot great. Try and find with with a USGI barrel dated between 1950 and 1967 - they are great shooters. Get a low TE and Muz to ensure the barrel is not worn out.
Be on the lookout for Garands that look too perfect - there are many people faking them now, especially in the stock area (cartouche's and stuff like that). For example, a real Winchester stock with the cartouche is worth $500 - for just the stock!!! You can see why people are faking them. If you go with a CMP papered Garand it will be legit.
Get Scott Duff's books on the Garand so you are informed BEFORE you purchase. CMP is a fantastic route to go as well.
Also check out Fulton Armory's web site and Scott Duff's site as well.
