Yost and Don Williams hi powers worth the price of admission IMHOMIne is now used, although in very good condition. I probably wouldn't buy it today at $7500, $5000 would be tougher call. Mine was "Yosted" just a few years ago when Ted still published a price list. (Think that's gone by the wayside now). I believe I posted photos of mine here a while back.
Sorry for the sidetrack, I'll shut up now!
