$300 a good price for 325/50/15 M/T drag radials?

looking at a set of drag radials to use to test fit them under the car... set has been down the track about 12 times, and never used on the street. is this a good price for some good used rubber? i was thinking about offering the guy 250 for the pair, see if that flies. what do you think?

happster: If your car isn't at least mini tubbed, those tires are way to big. I have 3" tubs on my Demon and run both BF Goodrich 325x50x15 drag radials and MT ET Streets 28x13.5x15. They run on 10" rims. Just something to ponder.
