I've never played the EM version, but I own a SS FBC, so have played heaps of games on it.
Bits I like are the different approach to the top lanes, the roll overs are arranged horizontally and make the plunger shot a good skill. The spinner is interesting and has variable behaviour, sometimes the ball gets 'stuck' on the grooves and becomes stationary for while before being flung off, other times it is immediately flung off. Some people reckon it's too random, I quite like it and it matches the BG so well.
I like the shot to the messenger ball for bonus multiplier increase. Multi ball is easy to get and good frantic fun - good in multi player mode as you can take over the previous players' locked ball.
Sound is pretty primitive for 1985, but seems to suit the game. The cabinets are decaled and seem to fade pretty badly, the orange t mould edging on mine has also cracked and deteriorated pretty badly.
Prices? One sold on ebay in Brisbane a little while ago for $800, which seemed pretty cheap. There is one that has been turning up on ebay in Melb, started at $2500 and not a single bid, re listed at $1800 and again not a single bid. Both of these looked to have faded BG, but otherwise be in fair cond. I reckon someone waving $1200 under my nose would tempt me to let mine go.
