Thinking about picking up a fairly decent HH. Don't know a lot about this title. Haven't played one since the mid 80's. Love the artwork and the backglass etc. Gameplay looks fairly decent for a 1982 pin. Looking under the playfield(s) and just in general, looks like a maintenace headache to me. Is this a tough machine to maintain and work on? Worked on my pins for sometime, so i know my way around them to a point, but this looks a little intimidating. Gameplay? Lastability in a smaller collection? Overall thoughts on it? Thanks.
