If you think its worth it, no one else should be able to change your mind.
With that being said however, I got a complete 4player Xmen, all original, pretty good sideart, 25" monitor, etc etc AND a 25" Midway cab with Tekken 2 in it (all working). I got both of them for $450. That is not bragging, I'm just saying, the guy I went to and a few others I visited had similar prices, so you may want to look around. I'm in NJ so it may vary by region, but I'd say look around a bit. Check the yellow pages for Vending companies, a lot of times the ones near me have a few games that they dont really need/want/know what they have.
