Anyone use WebTransact for CC processing? http://www.webtransact.net/pages/merchacc.htm is the site...their rates are very competitive, but even more importantly, the signup turnaround time is awesome! I have an application filled out for a different CC processor, but it'll take days to get the account setup; these guys claim to have it fully automated, and best yet, they use Authorize.net for a gateway?

Any experiences/thoughts?
