martys advice is spot on.
Last action hero is a good game.not too expensive. Batman Forever is a looker for sure, but plays real slow.
Getaway is a blast. etc etc

Play the games at Marks or ask a member on the forum for a visit. If Marty has a machine for sale, you can bet it will be real nice and working 100%.

That is very important when getting family or friends into a game. You dont want something that needs work or dies. The Dr Who pin is fun and the darleks are a blast. Maybe Marty could be a good answer for you. Have a look. His website shows the quality of workmanship. You couldnt go wrong there. 
So many bloody great choices with great members to help you out. Great hobby hey !
