IMO you are committing business suicide by not accepting Paypal. I know there are some fees involved but it's not bad if you work them into your prices. Some buyers will refuse to deal with you if you don't accept it. I buy and sell and Paypal is a necessity. It offers both buyer (especially) and seller protection.
Plus, a lot of buyers want their items fast and payment by snail mail will not afford them that luxury.
Just my .02, take it or leave it.
Good Luck!
