well, I bought the Blackwidow Filmscan35. Tried all manner of tweaking, but the results are very disappointing.
I would definitely NOT recommend this device, especially as it is very over priced at over fifty quid by the time its in yer mitts. A plastic moulding with two mirrors!
Now trying for a refund, so next report will be on Blackwidow's customer service!
So, its time to buy a proper scanner with slide reader.
