Recently I started doing analog photography again (as hobby), owning a Canon EOS 1N, 24-70mm f/2.8 lens, developing all films by myself in C41 with focus on cross processing. Since I'm owning an Epson V350, I'm thinking about getting a new scanner, perhaps a Reflecta ProScan 10T, Plustek OpticFilm 7600i or similar, in that price range.
My question is, "How much difference in performance can I expect to see?" Does somebody has experience with an Epson V350 and a more "modern" scanner for comparison? For me this is quite an investment, so things should be well-thought-out. In addition I'm rather new to film scanning (but not to analog photography).
I'm wondering if these newer scanners will provide better detail, greater dynamic range, more sharpness, and truer colors than my old V350 does - and if so, by how significant a margin.
I'm using vuescan and ColorPerfect, if that matters.
