I got enthused by the whole speed lens thing a few years back and built my own Graphic and Aero Ektar combo for around $400. The prices on the lenses and good Speed Graphics seemed to have climbed a little since then (but not hugely) while the adapter for the lens is now apparently readily available, but it still looks like you should be able to put one together for $600 - $700.

This auction seems to suggest that someone was prepared to pay $2500 for one, while this one is a bit cheaper and a touch more eccentric, but the seller seems to think that $2000 is a reasonable BIN.

Are they really selling for over $1000 on a regular basis? Have I missed something and the whole David Burnett thing has got even bigger? Surely this is all a few years old now. I also noticed that there are seven or eight Aero Ektars for sale on eBay UK, all from different sellers, which much be must be some sort of weird coincidence. Or maybe this is a variation on Petzval madness.
