WTB: PCMCIA USB2 & maybe F'wire

[WVZR1]

I'd likely be interested in a USB2 or a USB2 & F'wire combo PCMCIA card for an older laptop I'm going to try a Delorme LT-20 GPS puck with. Needs to be inexpensive, this is likely just an experiment!!
I understand voltage is sometimes an issue so I imagined using a y-cable to the "puck" from the PCMCIA card. Hey if you've got the correct y-cable I could be interested in it also!
