link to online arcade games mate, youll need to register if you want to record your high scores otherwise its free, has some classics on there http://www.arcadeboss.com/
Along the same lines - I can sort you with some NES and SNES roms if you're interested... If you're after actual full-size coin op machines, ebay is the place to go
ebay is not the place to go, its full of greedy bastards. 1k for a space invaders? jog on Joe! ebay has been fucked for about 5 years now, people think a second hand price is 75% of the new price, and they mainly get it too. I used to pay 40% for second hand gear back in the day, id rather buy new now
if its an original space invaders in original housing its probably worth 1k mate, ebay is full of collectors now
Anyone heard of Temple Clearances in Pallion, great little alladins cave i am going to keep poping in there from time to time he gets them in
