Yeah same here, not sure why they're so expensive. The only thing I can come up with is, with things that are produced in low quantities to make a profit you'd have to sell it at a marked up price.
Whereas a lot more people buy joysticks so although you're making a lot less profit for each joystick sold, you're selling a lot more joysticks than spinners. Same thing with academic videos sold to universities, they produce about 500 copies but they sell each one for about 300 or 500.
Yeah... I might consider this option later down the road.
As far ad the track ball.. so it may make sense for me to buy that arcade one and buy the adapters/encoders. Does this method, using the mini pac or converter, work well?
** also, has anyone had experience with the x-arcade trackball? What did you think? W/ shipping it's about 65 dollars... and so far I read good reviews.
