I had the same dilemma. A New Vaquero was out because of the small frame. So I looked at new BHs, but didn't like the quality of the frame fitting on the blued guns. Apparently they just slap the pre-fab grip frame and frame together, and you get what you get, overhang, sharp corners, and all. They can't grind anodized aluminim for a good fit to the frame, unless they then re-anodize it to cover the white. Stainless is a more durable finish, too. Once you ding anodized aluminum, it's over.
I looked at flattop all stainless BHs, but didn't like that they wouldn't handle hotter loads. I resolved to watch for an 'older' New Model Blackhawk. Week after week I called all the LGSs asking about used .45 Blackhawks, and all they ever seemed to have were Super BHs. Great guns, but not what I wanted. I even resolved to 'like' the billboard warning on the side of the barrel on older NMBHs -- something I hated before.
So last week I ditched work at lunch and went to my LGS to look for a used Blackhawk and what did I find? A mint condition original Vaquero in Stainless, 4 5/8" barrel, for 4 bills. I jumped on it. It would be cruel to post the pics here, like the thoughtless fellow above : ) but reading these posts makes me appreciate my good luck all the more. The guy who sold it to me said it was a 'good find.' Apparently!
Keep looking. There are several original Vaqueros on Gunbroker right now, but they're all over $500. One was $799 or something insane. But... they're out there.
