The vast majority go for a reasonable price. can usually pick up a decent student grade vintage horn for 50-70 donuts. Anything rare, Recordings, ANY flugal, etc. they get up there fast. One bidder i see often is R+++++3
When they are there one night, i just stop and wait till they are not there. Cause they get MOST of the ones i want. When not online and bidding, i can get them for half of what i would need to pay.
That bidder probably says the same about me;)
