Anybody want to share a tuner??

:eyepoppin I know I may get blasted for this, but what they heck!!! These things seem so high priced for what you get. Does anybody know if we could have a few people each chip in some money and buy one together and use it on multiple cars? Is there a limit as to how many different cars can be flashed from one programmer? It wouldn't cost that much to ship it between people... I just find it hard to spend $400-$500 to get a few horses, mainly I would just like to get rid of the throttle lag. Let me know...
