He has to speak for himself - all he says is, "There are better choices." The finish of the interior components isn't up to a lot of other pistols he works on, so I think he finds it more work. As you don't see the inside of a gun and it has little impact on function, for most people that's a non-issue, while for collectors it's a negative.
Paid $380 for a CZ85 Combat and put about $200 into the work and shipping. I want $500 for it with no takers. Best offer so far is $425, so I'll keep it. I'd like to buy a SIG P226 instead, because my SIG P220 shoots so well.
