One can find pythons in great condition around my neck of the woods for $2,500-3,000 depending on minor condition issues and extras.
Myself, I would have a really hard time paying that money for a shooter. Who is going to work on it, and where does one get parts? What is the current status of the gunsmiths at Colt, is it still safe to send a $3,000 Python into Colt to have their current line of workers fix a problem, or make it worse?
But if one has the means and desire then more power to them. Really, in the grand scheme of things if one's hobby is shooting firearms $3,000 as compared to paying $15,000 for a sportbike (which will be worth 1/2 the value in a few years) or something similar seems like a bargain.
