Trackballs and Spinners

[USSEnterprise]

Why are they so expensive? I mean, they are basically like computer mice, but set up differently. They seem relatively simple. Why?

1)
Because mice are produced  (and sold) by millions, every PC comes with a mouse, let alone the seperate mouse sales...trackballs (especialy arcade versions) and even more spinners are sold in very moderate numbers

2)
If you are talking about proper arcade trackballs (and spinners), those things are designed and built to be used in arcades where they get hit, kicked spit on etc. etc. AND used very intensively. This requires a very solid contruction. There is no comparison with home use. F.I.the rolls where the ball is lying on are metal, not plastic etc. etc. And have you considered the weight and size of the ball ?
The bearings have to be of better quality too, since you want the ball (or spinner)  to keep rolling for quite some time, not neccesary for mice.

And there's probably some more reasons...

my guess would be that its just that mice are produced on a industrial scale, whereas there isnt enough demand for spinners.

trackballs i have no idea why the arcade ones are so expensive, but ordinary pc ones arnt and you could allways modify one of them.

IMO its not worth buying spinners off the shelf, you may as well just buy any old mouse and a good looking knob and modify that into one

I just found a place where you can get a $30 USB spinner, but I need either a PS/2 or serial,  on an opti-pac.

am i right in understanding you woulnd't need a opti-pac if the spinner is ps/2 or serial?

[USSEnterprise]

or USB, yes, you wouldn't need one

[Jollyrob]

ah, i see, you intended to put "or" an optipac...i said that because you put on an optipac, i was thinking you wanted a ps/2 trackball to use with an optipac
