If $$$ are short (and boy have I been there before), I would suggest looking into what you are wanting on-line. I know my man at my pro shop would hate me for saying this out loud, but the fact is you can find stuff on on-line stores much cheaper than you can at the local pro shop. I know you can find the GTs cheap and if you know exactly what site you are looking for, I am willing to bet a weekend of hunting that you will be able to find it on-line cheaper than at the pro shop. Just a suggestion, I hope you get it all set up and zero'd in.
While this is sometimes true, usually it comes out about the same when you figure in labor. I can only speak for the shopI work for, but if someone were to bring in accessories bought elsewhere, we're gonna charge them....I think it's $25/hour to install it. So unless you can get a really good deal, it's not normally worth it.
You're probably going to need around $250 for what you want to do. Maybe closer to 275 once you figure in tax and all that....
