I recently aquired one with a busted monitor, but the cabinet itself is virtually like new with all original parts. It has never seen the abuse of an arcade as it was originally bought as a gift for a dude from his wife. It has been regularly cleaned are cared for. In fact, it was during one of these cleaning sessions that the monitor went out. So... what's a Space Invaders in PERFECT conditoin worth (sans the replacement monitor and perhaps a minor scratch here and there)?
