Steel lugged frames are just a good idea that isn't going away any time soon. NAHBS was sure proof of that.
They work. People like them. People are willing to pay for them. Basic stuff, but it still surprises me once in a while.

I recently listed an Ironman for sale. The buyer was in SC, I'm in NC. His dad, a Trek 2.1 owner, came by to look at it for him, though he "wasn't into steel bikes"......or so he thought...(evil laugh)....
We walked around the garage. We rode out into the area. We came back. He made calls. We negotiated, but not much. (I try to be fair.)
He left with the bike. He wants one in his size.

Another guy came by for a fitting, to see what he wants. He wanted "aluminum with a carbon fork, or maybe even all carbon." He looked. We rode. "Steel will do."

After reviewing his budget, "maybe I'll get two." ...(evil laugh)....

World domination, one bike at a time. Or maybe I need to raise my asking price.
