The problem for me is the $$. I have a job, but an expensive habit (a family) that requires all of my $$. So, I am trying to build a controller on change I find in the couch, stuff I have floating around the house, and anything anyone will give me. However, I will not beg or steal. So I am just trying to find a very cheap alternative to a arcade trackball (since $40 is about all of the $$ I could scrounge up for the whole project and I only have about $5 for my trackball AND spinner). So I have been trying to pick up a good trackball substitute on eBay. If anyone knows a cheaper trackball resource than eBay, let me know.
