http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230651054749I bought this to try out for my MAME cabinet and don't like the feel. I never installed it. I bought the optional hard spring so both that and the original spring are included. Comes in the original box with CD and instruction manual. Guaranteed to work perfectly. Please feel free to email me with any questions. I ship FAST!
