RE: first bow
Your pro shop doesn't let you shoot a bow before you buy it? Not all shops have a range, but most have a target set up a few feet away that you can test a bow on. How do you know which is better for you if you don't shoot it first set up to your specs?
If this is how your local shop is then it's not a "Pro" shop, it's just a sporting goods store that sells bows in my opinion.
I am also of the opinion that if you go to a shop and they spend time with you letting you try different bows and adjusting them for you and explaining things to you that you should probably buy from them. It seems like a shame to waste thier time and abuse thier inventory if you are just going to go online and get one to save a few bucks. Especially when you need something adjusted or fixed and you have to go there anyway. Expect to pay top dollar in that instance for the service. This may be the very reason your shop doesn't let you shoot them if that is the case.
And if your local shop will not let you shoot a bow before getting it, find another shop. Even if you have to drive a few hours. Call ahead and make an apointment if you have to and to make sure they have what you want to look at and will let you shoot them. I would drive out of state for a good shop with great service and inventory. It will be worth it in the long run cosidering the amount of money it will cost you when everything is said and done. Let us know where you live and I bet someone on here can suggest a good shop for you. Might not be right down the road, but at least one in your state maybe.
If you were an experianced shooter you could probably save some money on the net, if you knew what you wanted already. However if you are new I don't think the savings will be that great. By the time you pay shipping, pay a shop to set up and tune your bow, and maybe get a few lessons and pointers I doubt you will save any money at all. These are services that should all come free with a bow purchase at a decent shop.
