I owned an M1 .30 carbine in the 1980’s but did not like it. Mine was made by IBM, the computer company. I found it was NOT that reliable, so I sold it, with sling, cleaning kit, and bayonet, for $180.
I just bought an Israeli Arms version with a crooked front sight for $350, and used ones in decent (not great) shape are going for $650 - $900 (paratrooper model) in my area
