I found a used dan Wesson in 40 on gunbroker awhile back. After some initial fiddling with bullet profile, load length and mag selection it's been 100%. It's a long ways from the cheapest option as there weren't many made so they carry a premium cost. Overall I've been satisfied, though if I had it to do over I'd have gone 9mm minor. More often than not the extra round(s) outweigh the scoring penalty, at least in the matches I've shot both locally and at several larger matches including last years WSSSC and this years Area 1. Less expensive initially and less expensive per round. Not that cost is a huge factor but it's there. There's also a better selection of pistols available. If I had to do major I'd have gone 45 knowing what I know now even though it would have been an additional caliber. Again, more selection of guns and (generally) less finicky than either 40 or 9. YMMV.
