Check in some of the range postings or in used gun lists. Sometimes you'll find a good example of those guns available and unmolested.
Retail on a Baer Wadgun is $1890. Add $300 for the 1.5" accuracy guarantee. You could call Joe Chambers, Jerry Keefer or Greg Derr and see what they could do for you. They are bullseye 1911 smiths.
On Gunbroker, some sites are selling the Baer guns at very good prices...a PII for $1560 last I looked. You can shoot it with open sights for awhile then have a mount fitted by a good BE smith. Just a suggestion.
