People seem to be asking between $3000 and $4000 for the reissue PS-10's. Unfortunately, Ibanez has issued several versions of the PS-10, so it's hard to price these things. Original PS10's from 1978 in unused condition are getting upwards of $10,000. I wish I still had mine.
The PS-10 II were the korean made guitar, so it won't command as much money as the LTD or the Classic.
