It's been a few years, but I watched an 8 point palmer go for $900 on eBay. Gus made the forearm, but the cue is a palmer. Gus sold forearms to various builders, Dale Patten is one that comes to mind. His cues don't command much despite the pedigree of parts. Palmers go for more and a Gus forearm adds some value. I'd say $1500 to $2000, but that may be high. The cue market peaked a few years ago.
