Track ball 'mouse' for Sun?

[mark galbraith]

We are looking for a substitue for the normal mouse provided by Sun.  We
are looking for a 'Track-Ball' type device, similar to those available for
the MacIntosh and IBM PC.

Does any one know where we can get one; and if so, the approximate cost of
the device.

Please e-mail to: {....}!uunet!deltam!trackball
I will send a summary to anyone who is interested.  Send inquiries
to: {....}!uunet!deltam!trackball-inquiry

Thanks
