What are good free-signup payment gateways to use on your site?

Thanks

Have you tried looked at Paypal?

Paypal, moneybookers are free you can give them a try.

Only thing is they charge you for the transactions you do.

PayPal recommended :)

Personally, I have integrated PayPal, MoneyBookers and Bank transfer payment gateways on my own sites. :)

Have a nice day,

I use Paypal, MoneyBookers and Google Checkout ( Mainly as an alternative to customers that don't like Paypal). And we also accept credit cards direct, but that is not free.

try 2checkout its fast and easy :D

PayPal, AlertPay, and Google Checkout (haven't found that one popular)

Paypal, moneybookers. They both charge a percentage of the total transaction. Does you bank allow direct money deposits. If yes, then it will be good if you can deposit the money directly to your bank account.

Moneybookers and AlertPay for Eastern Europe. Otherwise PayPal.
