My opinion... (i like challenging games the best)
I too didn't find FT very good at all
TAF is OK but way too easy in my opinion, i've completed the mansion 3 times in a 3 ball game. Hadn't played one for 18 months and on my 2nd game completed the mansion twice. That said it still is a good game.
STTNG - i would keep it over an TAF, great with LEDs and excellent sound, good rules
TZ - absolutely awesome game, quite difficult but achievable to get the final mode
TOM - i've got one in fanstastic condition and would probably keep it over TZ (even though its a slightly easier game, its super fast - also EVERYONE who comes over really likes it, regardless if they've ever seen a pinball machine before or not)
Whitewater - as others have suggested, this is one of the best value games out there - do yourself a favour and have a bash on one for a while, still have not been able to get the elusive vacation jackpot - this and TOM are the two machines my wife says can't go anywhere!
Jurassic Park - definitely a very good game, although not quite as good as Whitewater
