Non-Logitech Wireless Trackballs available?

[fbrdphreak]

Hello all
Wondering if anyone knows of a wireless optical trackball, that specifically has a SMALL, integrated USB receiver. This is like the types used with newer wireless optical mice, specifically designed for notebooks.
Here is the style of trackball I'm looking for:

However, I would really prefer a USB receiver of this type:

The picture of the receiver is smaller, to the right side of the page.
Any help would be greatly appreciated!!

nope, i have the first one you link and its awesome, had it for about 4 years.
why do you need a small receiver, that one is pretty small as is.

I would ideally like to use it for my laptop. Trackballs are great for lappies IMO, since u don't have to move the trackball unit itself. But a "mobile" wireless one would be awesome My friend has the same wireless one, and it does rock, just wish it had a small receiver for a lappy
