If the playfield is in good shape it's a steal at $1700. Most I've seen are around $2500 and up. So even with some cab condition issues you should be okay. Regarding playing, everyone likes something different. IMHO the game play is more fun that T2, I love the metal ramps, and the game in the back box adds some fun. It's not the deepest pin and the Arnold call outs "shoot here" can get a little annoying. But it's a Steve Ritchie, the King of Speed, and a pinball icon. Plenty of parts available for it.

Ahh. I haven't seen those but I haven't really looked either. Good luck. Maybe call Stern and ask them. Might be worth a shot.
