So how does one go about choosing an Authorizenet reseller for credit card processing services?

You certaily cannot make an intelligent choice based on their website.

There seem to be hundreds of resellers out there.

Any sanity to the process?

Thanks,

Contact a few, see how long they take to respond, how good their customer service is and whether or not they will work with you on the price.
