Does anybody know of a good credit card processor to download or purchase?

Be leary of authorize.net, you will also have to also have a merchant account----more charges. We went thru charge.com as our merchant account, our bill started out about $30 a month and ended up about $60 in about 6 months, with minimum usage. Then there was a hidden company that nobody told us about til we got the bill. typical credit card BS. I looked into Verisign and they seemed to have a good deal going, a certain yearly set fee for a certain number of transactions per month. The customer service was alot better and more informative when I talked to them, which was another problem we had with autorize.net. Thats just my personal experience, others may have had better.

I offer both PayPal (https://www.paypal.com/) and I used Card Service Sales (http://www.cardservicesales.com/). Offering a couple different options for people to use can help increase conversions (basically - try to give people as many ways to give you their money as possible). :)

Cheers.
