If you haven't already gotten one or want more, you might want to check out some of the computer shows that travel around. I got two of them for $2 a pop at a computer show and another two at different rummage sales for $1 and $.50. I always keep my eyes open for this type (doesn't matter the brand- I'm on a dell right now, but same style) when at garage sales, flea markets, computer shows, stores, peoples houses, etc, etc, etc. I used to have sore wrists constantly, but no longer have any problems.
