I doubt
ShopGoodwill.com encourages bidders to inspect auction-items beforehand, but most of their Omaha online inventory is at the 72nd & F warehouse.
Here's a vintage
Gibson lap-steel, with twin 8-string necks, case and detachable legs. I've bought gear from John (the seller) before. His asking prices are high, but negotiable. He's in the Florence neighborhood of Omaha.
Here is a 10-string, single-neck pedal-steel... but unfortunately it's in Kenosha, Wisconsin - just north of Chicago.
I'm unfamiliar with the Certano bending hardware. If installation requires drilling/routing, it might hurt re-sale value. Do your string-benders work with either 6-or-8 string lap-steels?
