I would prefer any payment through Paypal, but I might be willing to negotiate another option. Trades are discouraged unless you've got something really good to offer!
P.S.
I'll cut you some slack on pricing if you buy multiple items
EDIT:
I'm willing to to trade with anyone that has a high capacity Compact Flash card (4GB or more), or a TI calculator
