fyi gender change adapters are stocked by "radio shack" they run just under 10 bucks! also newegg.com is excellent for getting weird stuff.if ur working on a laptop,unless its really old and does have a serial port u don't need a gender bender you need a 9 pin serial card adapter.......but before u order u need to determine if u have a straight pmcia expansion slot or a express(narrower card) hope this helps.the whole usb thing with these plotters is mind numbing.....by the way with shipping my pmcia 9 pin card ran 40 bucks from newegg.com hope this helps
