Price Check Bulg. Mak 380 ACP w/ threaded barrel

What's a good price for a Bulgy Mak /w a threaded barrel in 380 ACP? I am fairly sure it's threaded to 1/2x28. I don't want to undersell, but I also under want to overprice it. I tried looking around the forums here, but couldn't find an example of one selling. I know Chefur makes barrels for 9MAK for around $175, and I know Bulg. Maks go for ~$350-$400 on a good day. Just not sure what an already pressed in 380 barrel would go for. Thanks in advance.
