I picked one up late last year on a tip from Magdump for $250 , thru PSA. Looks like they are out of stock now, but you might want to keep an eye out in case they come back around at that price.
I grabbed a second one at that price once I got the first one in. I actually got it for $229. All steel quality goodness. Hopefully they’ll roll around again. Same thread adapter as my P-22’s.
If I see another deal on those I’ll be sure to post it.
