Forgive me, I realize this may be way OT, but since this cn be used for radio experiments, etc. I thought I would share this source of parts.

Arduino boards and Shields at bargain basement prices + no taxes + free shipping.

I've order several and had no issues with the boards received.

I used one for a project I did on Caller ID, and getting ready to play with another to decode WX warningdata from a VHF receiver. (S.A.M.E.)
