I did! I sent him a carefully worded message last night, asking why he had two distinctly different prices on this drumset. I also told him that I had no selfish interest in buying them and that in my professional opinion as a longtime drummer and self-appointed "expert," he had very little chance of getting $1899-2500 for the drums. I made it clear that I was trying to help him sell the set in good faith. No response yet. I would bet he'll either ignore me, or tell me to go to hell.
I also should have told him to lose the plastic covers on his couch! LOL!
