Hey guys, I'm looking for an external modem, must be working(of course), and have the power adapter. Manuals unnecessary.

I'm looking to spend no more than $30, so if you have used one you don't use, let me know?

I also have a PCMCIA 56K modem I've never used-brand new in box. I'd be willing to trade if so desired, otherwise, consider this being sold for about $40?
