I’ll second the Epson range. I have the V750 and I have been very pleasantly surprised by the quality of scans I’ve had from both 35mm (negs and trannies) and 120 film. Not cheap – it’ll cost you £600 ish but it will scan to a very high standard. Otherwise, it’s off to The Pro Centre in London to hire their Hassleblad Flextight drum scanner at £50 per hour + VAT. There isn’t much between as far as I can tell….

Like I say, I’m no expert but I am well pleased with what the V750 gives me.
