I have a line a an older Vaquero, 5.5, case colored, 45Colt, w/stag grips for $499 - excellent condition. I typically only buy BH's, so I do not know much about Vaquero's is this an average/fair/good/great deal?
I would say at least good. I sold a .45 5.5" bright stainless Bisley Vaquero last year for $630. Check completed auction on Gunbroker for more recent pricing.
