Though a part of me agrees with BM regarding some online resources such as Eders I also have to agree with the pro shop comments. Something that alot of folks generally assume is that all pro shops cost more than mail order catalogs like Cabelas, Bass Pro, etc..
That is not true.
I know of at least two local shops that carry their bows and most accessories at the same prices that Cabelas does. I am even aware of two bows in particular that those two shops carry for $50 less than Cabelas.
Plus, with knowledgable pro shops you have someone there to ask questions to or just bounce ideas off of.
Just some things to think about.
