Almost one year ago I had a chance to grab a baritone Konablaster off of my local Craiglist for only $175, but the seller was a bit fishy when I visited him and something was really off (really sketchy neighborhood), and my gut told me to walk away.
I've questioned that decision in retrospect a few times since. However, I still look for one of these, every once in a while too.
Still not a bad deal if you're ok with the long scale length - 22"
I ordered mine custom with 19" scale and extra tone controls for not a whole lot more.
