I know it can be done cheaper, and the ebay ball and soring aren't that great, but they do a decent job and it is worth the time I save to buy one of those rather than run all around town to piece something to gether...
Then again...I won't be using a ball/spring on my current set-up.
Oh ya, I bought turboxs controller (the kind that has fine and coarse boost setting) for like 30 bucks off ebay. The guy didn't realize it was nicer than the base model...and didn't list it as such, but you could tell in the pic that it was the better one.
