I had no trouble ordering a twin-pack from RadioShack (p/n 25-3103) about
6 months ago... except for the fact they don't send overseas (so my
cousin had to forward it to me. They are the original type. I also
ordered a Deluxe Zoomer pen at the same time - that was even cooler.
So if Radio Shack is out of them - I'd invest in a full-size stylus, the
experience is better than the inconvenience. (See the back of Pen
Computing Magazine for ads for them).
