The Mayflash adapter is easily found around the web.
If Amazon.com isn’t your suit, Play-Asia also carries it. It’s under the PC & Mac section, sub-category joypad converters…
Don’t know why most Americans wouldn’t try Amazon first, though.
Thing is that even if you don’t have a credit, you can buy a $25 Amazon gift card at many stores (my local Giant Eagle sells them) and use that as money/credit on Amazon.com. Works exactly exactly like a debit or credit card but with a fixed limit.
Buying gift cards is a good way to avoid the credit card monster (interest rates!!!) and build up money towards gasoline discounts, too. For every $50 you spend at Giant Eagle, for instance, you get 20cents off per gallon of gasoline.
Gotta make those dollars count for as much as possible! Most of us are aware that current situations call for being extra-tight and smarter with money more than ever now.
