I have never played TZ but I think IJ is better than ToM. ToM is pretty and has good flow and toys but the game play is just too simple for me. My buddy has it and I get bored after a while.
IJ has some tough shots like the mode hole and the PoA. You have to hit them just right. It also has good quotes and lots to do. And it doesn't feel like a widebody to me because the lower part of the playfield is narrowed to normal size.

Most of the hate is for Sterns IJ. It wouldn't be in the top 5 if there was a lot of hate for it. Some people may not love it but there are few who hate the Williams IJ.

I would at least go look at the TZ. If it isn't worth it then you have that piece of mind. Just don't buy it just because you drove 2 hours. Try to remain objective. I know it is hard when that shiny candy apple is dangling in front of you.

Paypal is safer than sending cash, check or money order. At least there is some buyer's protection with Paypal. Anyone not willing to take Paypal is suspect. Take it from someone who has been burned. I will never buy something on ebay from someone who doesn't take paypal.
