Good luck getting money onto Bitcoin (for Americans) without using¹ a payment network controlled by Visa (Visanet) or the Fed (Fedline, Fedwire).

Bitstamp is pretty good. The only problem is that the cost of an international wire is a significant part of the purchase price unless you are converting at least 1000 USD.

As far as I'm aware, companies don't offer direct convertibility of funds from a credit card to bit-coins.
