Guy here oically has a pre model 27 3.5 inch for 1500.00. Has some holster wear

Same guy has a 27-2 3.5 inch that is in desperate need of a reblue. Hes asking 950.00

My question is im kind of interested in the -2 because I can afford it. But after sending it for a reblue and finding a good set of grips. How much would I be into the gun?.. would the cost be justified. And would the gun bring good money in the future knowing it had been reblued??.. thanks for the help
