I found a $5 one at Ross the other day which is both a standard pen and stylus. Works great so far. The brand is Oloaudio. Hmm not sure if this is made in China.. Threw away the packaging already. But I believe all work the same. Some look better than others and of course the better it looks, the higher the cost. I suggest getting one with a rubber round tip. I've used one where the tip was more squarish and spongy and those tend to leave a dragging feeling rather than smooth.
