Game shops have a bundle of xtras (Xploder or somthing) - there's a x-port type thing in there, along with Memroy card manager and more.
If you can't pay on a card to order it online, try cheque or money transfer or something to psxservices. I reckon they're trustworthy - I had a query about a lead I got from them, they had no problem offering a refund if I wanted (I didn't).
