I suppose you can't blame a person for trying to get maximum value, but I must agree, many are priced unrealistically.
However, I've bought and sold numerous arrangers from the good people on this site, and have not been disappointed even once.
We are so fortunate here in the U.S. to be able to purchase new gear, and some used, from FrankieV. I makes it easier to move the gear along later and not get killed on the price.
I'm selfishly glad that everyone doesn't know about his operation!
