I bought one in June for $350 that included 100 rounds of ammo. It was in decent condition with a mismatched bolt. I also wanted a shooter. Bore was very good, but it would barely pass a field gauge, so I replaced the bolt head to tighten up the head space. It shoots good. I'll be reloading. Steel case ammo can be hard on extractors.
Prices tend to fall into the $350 to $500 range in my area depending on condition.
I would advise you to look at the bolt on any Enfield you plan to buy. Bolt heads are numbered 0 to 3. If you have a 0 or 1 then you have room to move up to a 2 or 3 to fix head space issues, although finding a #3 bolt head is nearly impossible these days. If the gun already has a 2 or 3 bolt head, I'd check with a head space gauge before buying. Also rotate the bolt head and make sure it does not rotate more than 20 degrees past vertical (the original one on my rifle did). Bolt heads that over rotate pull all the pressure on the bolt head threads, and will wear quickly resulting in head space issues.
