I reread the ad and it seems to indicate a quantity of two, making the price a good deal, for anyone that can use dryers with 18 in. belts.
It's a bit on the narrow side, but good to keep around for backup.
If I was a whole lot closer to Abilene, I'd probably pick them up and keep one and sell the other.
Does make me wonder though. He spelled them as Black Body, not Black Buddy, hmmmmm....are we talking about the same thing?
