If I was in the position to spend that kinda cash right now, I'd have to go with LOTR. I've played both, and just seems you get a lot more bang for your buck with LOTR. The way I see it, I can get a quick fix game for a lot less money. If I'm dropping good money, I'd rather spend it on something deep, with a lot more life. Seems LOTR would last longer in the home environment.
Just my 2 cents. You can't go wrong with either. Both are gorgeous examples of how awesome pinball can be.
