I don't think it's in poor taste. It may piss off the owner, but ya know what............it pisses me off overpaying for something!

I bought a new set of sites this year for $46 on ebay. I took it to the shop and had them put on my bow and I bought 1 doz aarows, new string, and a new WB. I'd say he made out OK. BTW, the same rest was $86 at the shop.

I also don't have a problem buying parts for my car/truck and taking them to a mechanic to do the work.
