$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?

Are you talking about ET Street Radials or ET Drag Radial? I don't see where the make a 325/50/15 Drag Radial.!
