I'm looking forward to when this guy writes in with his horror story about how Paypal froze his account and stole all his money.
It appears that inconvenience cannot be created or destroyed; the merchant account people frontload the inconvenience, and then, satisfied you probably aren't a crook, leave you alone. Paypal backloads the inconvenience - signup is easy, but then at any time they might freeze your account and steal all your money.
Seriously, there's a huge market for a transparent, straightforward merchant account provider.
