RE: filmscanners: Too picky?

I have many lazy or perhaps overactive sensors on my Scanwit 2720S (the
infamous yellow stain with negatives or reddish stain and tram lines with
positive film) and I don't find it acceptable, but the warranty period is
over and the people from Acer that did the repair suggested there was no
problem, others from Acer acted as if there was no solution. So I live with
the problem (don't have money for some quality scanner). I wouldn't buy the
Scanwit again and I would buy something wit dust removal, since even though
I use the same antistatic cloth used by film processors to remove dust from
negatives I still get 3 to 30 dustspots on every scan. Perhaps our
living-room is too dust for filmscanning and the scanwit has acquired a fair
amount of dust internally.

BTW. Its not 2 and 2 and 4 pixels, but a lot more with my scanner.
