Amen to everything IF52 has put down. The market, or more so the consumer is driving the price train.
Curtis at Retrotec made me a Half frame in 2010 for under $1400. After spending some time with the bike I have a hard time buying (no pun intended) the "all custom" IF marketing. They make an awesome frame and paint is as good as anyone else, or even better. But last time I checked it is demand that drives everything.
Look at Harley Davidson. Their sales and pricing went sky high until people stopped buying their bikes. Now they can't get rid of what's on their lot. Add to the mix they had so many different models competing for sales and the company is hurting. Does IF need to make a full carbon bike? I think not.
As posted by others here on the thread, there are plenty of top notch frame builders (Retrotec/Inglis, Sycip, Hunter, Black Cat, Coconino, etc.) that truly give you what most IF buyers really want, a unique bike that rides tops.
Everyone manifests on the "Made in Somerville" aspect of FC bikes. Why is that? It's when the company was at its roots and quality was killer. New York bikes are generally worth less in resale if I'm not mistaken.
History will repeat itself here if all folds as the gouge has been put out.
