Gun shows and Armslist. Armslist has treated me well.
We've got a run-of-the-mill gun show at the county fair grounds 4 times a year, $5 to get in the door, is usually worth it just for people watching. I've made it to "The Largest Gun Show in the World," Wanenmacher's Tulsa Arms Show, in Tulsa, OK 3 years running, it got canceled this year due to 'rona. They do it twice a year, Spring & Fall, and there are plenty of Garands there every year. If you're not picky about provenance, matching parts, or a rare model, you should be able to snag an "armorer's parts bin" M1 Garand for around $700.
Story time:
I wanted an IHC, like since I was in high school and learned that a tractor manufacturer once made M1 Garands, if I was going to get one it was going to be an IHC. I turned down many other Garands, holding out for "the one." I was finally at a point in my life that I could make it happen, and I'd been passively looking for 3 or 4 years.
I took a firearm newbie friend of mine shopping for his first shotgun at the local gun show, so he could get his hands on a lot of things. We'd stopped to admire several Garands, I was really tempted by a nice parts matching Springfield, but I told my friend, "no I'm holding out for an IHC, if I ever find a complete one, I'm buying it." It wasn't 5 minutes later, maybe 3 or 4 tables down, a regular guy, non gun dealer, had bought a couple tables at the show, to unload some of his private collection, a bunch of WWII & Korea memorabilia, including several Grands and M1 Carbines and accessories. The clouds parted, and a light shined down from Heaven, there it was, a complete, parts matching, immaculate, IHC M1 Garand. There was a guy ahead of me, he had been haggling, and had gone to an ATM to get more cash. However, I came prepared, as I always do to a gun show. We discussed price, some brief negotiating, I handed over cash, and was a proud owner of an IHC M1 Garand!
About a month later, I was at the Tulsa Arms Show, trying to get a better understanding of some of the roll marks and cartouches on my Garand. Just showing the old dudes with dozens of Garands for sale, photos of my IHC and asking questions, they all wanted to see the photos, scolded me for not having it with me, and offered me 3X what I paid for it. I didn't really have buyers remorse, before, but I did have some post purchase reservations, not about the Garand, more about the amount I spent, it was not an insignificant amount of money to more or less impulse buy something on the spot. After talking with the "Garand experts," in Tulsa, all reservations had flown out the window.
