Up for grabs is a Clearly Superior Technologies LTracX Large Trackball w/Scroll, model CST2545-5XW-RC. See the
Fentek site. Fentek, which is the company I bought from, lists it as the MLTRACXP2JSUB (it looks like the MLTRACP2JSUB picture) which has the two extra jacks at the top and 800 to 3200 CPI. Original buying price was $165. Asking $145, comes with original box and CD's. I'll pay for standard shipping if its to the lower 48 states. Anywhere else, you'll have to cover for it.
Nothing is wrong with the trackball and will arrive looking virtually brand new. I'm just finding that after using it for two months my wrist is starting to hurt due to my desktop setup.
I don't use eBay very often but can list through it if preferred, you'll have to pay the extra costs and shipping.
