coin acceptor

How hard would it be to integrate this: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&rd=1&item=250205103520
With an arduino?

Could it be connected straight to the digital pins?

It would be a lot of fun trying to make it work with an Arduino, you might want to ask the buyer if there’s a spec sheet available.

I think I’ll get one and just have a go anyway! Its the cheapest coin acceptor I can find! (On a different forum I’ve been told it only accepts 1 coin and is actually called a coin comparator (that matches a coin to a sample))

But I can’t see ANY search results on the internet with coin acceptor/validator/comparator/mech and arduino in the same sentence !
