Here is a list of Paypal Alternatives:

Google Checkout:  Google Checkout holds sellers funds for 10 business days for new accounts. Then the funds are deposited into your bank account or check. This hold is removed after 60 days of your account being in good standing. I LOVE Google Checkout!

MoneyBookers: Not so popular in America, but is popular in AU.

AlertPay:

2Checkout:

AMAZON.COM - MY # 1 recommendation over Paypal / Ebay.

National Merchant: Integrates well with Ebay and you get paid VERY quickly.
