It’s a buyer’s market. Cane rods are expensive primarily because of the “collectability” – – – association with an individual builder, low numbers produced, no longer available, condition, etc. Conversely, virtually all graphite rods are “without heritage”, being built in a factory (however well designed, built and performing they might be). The analogy might be a “best gun” double shotgun vs. a Remington 1100. Both work equally well, perhaps the 1100 even better. But there is a couple of orders of magnitude difference in price.
Plus there is the warranty thing, and wide availability of fine-casting $100 rods on the market today.
Unless you really want it, or owner is really proud of it, $100. $150 tops. And then only with everything in pristine condition – – – primarily no sign of any dings or nicks on blank that might lead to a fracture.
Or unless that heritage is there, e.g., the rod was personally owned, built by, inscribed to [insert famous personality here].
But I have an old 490LL 4-piece that has many memories associated with it. You couldn’t touch it for $300. OK, it’s usually a buyer’s market.
Good luck
