Will check them out. I have a very old Microsoft optical trackball mouse that was the original from ten years ago--and I swear I will throw a major fit if anything happens to it. They are about 200.00 on eBay now and were about 50.00 when I got it. I only use trackballs at home and my right wrist--or is that wright rist??--thanks me for it daily!
