I'm just not sure why some people are so set on PayPal.
An alternative that's more generally accepted is Dwolla (or depending on where you have your checking account there are other alternatives).
If you've got funds in a Dwolla account, you might as well use MtGox. It's a piece of cake once you get the funds to Dwolla.
Can I upload funds to dwolla straight from my Card?
Nope, only bank transfer to dwolla.
