I've got a Kensington Orbit Trackball met Scrollring, love it..... but it has one shortcoming, the 3rd mouse button is missing. The solution is to press the left & right button at the same time, but it doesn't really work well, especially not if you have apps where you have to press and hold the 3rd button.

Looked at the Kensington Expert Mouse Optical Trackball, but it's too expensive, I don't see why it has to be priced so high compared to the rest.

So, I did get a Logitech Wireless Trackball M570. It's different from the Kesington ones, you control the trackball with your thumb. It needs getting used to but works well.

I don't use the Kensington anymore, since I got the Logitec. First of all the Logitec is much smaller. Secondly it has more buttons and options. Thirdly it is wireless. Fourthly it just works better for me. With the Kensington, your hand still moves around a lot. When you use the scrollring, the trackball and even the buttons you have to move your whole hand..... a lot. yes, much less then with a mouse and more efficiently, but still, a lot of movement. With the Logitec there's much less movement. My hand is steady, on the mouse. My thumb moves around, the rest of the fingers only press some buttons or control the scrollwheel.

I'm using a trackball due to a muscle disorder. I can use a mouse, but it gets painful after a while. A trackball is much more comfortable for me and having used them for 2 years or so now, I don't even want to use a mouse anymore. I just wish I had discovered a trackball years ago.

I'm using my trackball with Poser, Hexagon, Vue and so on without a problem. Surfing, windows operations, making presentations, windows explorer, dtp, it all goes well with a trackball. I'm even able to use it with Photoshop, DrawPlus and such, no problem. Since I switched to a trackball, I hardly use my Wacom Bamboo tablet for drawing and such.

I can recommend one, just a bit of advice, if you get one, take time to get used to it. Took me a week or so to get used to it. You use different motions, different muscles. It even may feel a little discomfortable at first, but once you get over that, using a trackball is actually a muscle relieve and very comfortable compared to a mouse.
