i wonder how would that influence the price you list, if i tell you i bought my super ikonta III with Novar for 20 euro 🙂
No really. What i miss on your list is the approximate numbers of sales you base your statistics on. Like, you write there the price of a SI III "with Tessar or Novar" as $325 at least. I wonder how many sales you used for this statistics, especially with the Novar version which is relatively rare to see.
