yeah, these seem like pretty high prices, not to be negative but just for people who would be looking to compare prices:
For example, I picked up a T2 in really really great shape and plus it's a diamond plated playfield, beautiful cabinet, shopped out, for 1,900. Plus, in my area, pins are above the average market price, so in your area I'd imagine the price would be even lower for a comparable pin.
As for the Taxi, it sounds high to me as well, but the Taxi I got was a grand less but probably in not as great condition as what you have stated in your ad.
