I too am a Bullseye shooter, in fact since 1978. I'm now 81 and still shooting Expert scores. Anyway, I think I have 5 Salyer built 1911 wadguns. All have Kart NM barrels and shoot very, very well so I can recommend him highly. I'm sure if you talk to Dave, he will have some good advice for the path you take. He might even know of a pistol someone wants to sell.
Buying a used wadgun is generally a good way to get going with a known good pistol if its not about worn out and needing a rebuild. If you can find a lightly used Springfield Range Officer (might get one for $700) you could start with that and when your skill level increases and you are enjoying the sport, send it in to Dave to rebuild. Take a look at this website
https://www.bullseyeforum.net/ Thats where the Bullseye shooters hang out and you can pick up a lot of good info.
