Im guessing that the Hyper game is a Williams HYPERBALL
http://www.ipdb.org/machine.cgi?gid=3169DDStoys has one of these.. hed be best to tell you how easy it is to get parts etc.... strictly project this one and size of project unknown.
Personally, id be looking at the 2 pins alone and having the Hyperball thrown in as a parts machine to sweeten the deal up a bit.
Not sure id pay $2500 though.. $1500 for the 2 pins ( thereabouts) and a bit extra if you decidse to pick up the Hyperball... $300 tops on this though.
Thats where id be going.. always someone willing to pay more though
