An earlier post of mine on the Takahashi FSQ 130 thread - looks like it was a reasonable guess (unfortunately!).
My guess - FSQ 106 is about 1.6 x price of nearest aperture "normal" Tak (TSA102super). Based on TOA 130 NFB price of $8490 that gives a price of about $14000 (to the nearest thousand). God almighty - I might have to go back to work!
