Hi there Peter,
Yes I scanned these my self
- it was actually using a scanner that I have access to (Don't actually own one myself - although I'm considering it quite seriosly as I love working with film).
The scanner is n Epson Perfection V700 - and Ive got to say - its pretty nice.
Ive used a few of them and this produces very good quality scans, and goes up to about 6400 dpi (this particular scan was a 16bt gray-scale 6400 dpi -> 8bit gray scale 3200 dpi reduction).
The good thing about this one is it is FAST.
Other scanners I have used can have tedious warm-up times - and do take a while to get through the negatives.
Downside to this one is its priced around 800 - 1000 NZD ish (from what I can remember).
Im not sure where your located so I wont convert that, but its a reasonable chunk of money (though I think it would be worth it to me).
You can get them cheaper though - ive seen a few smaller ones that do about 1800 - 2400 dpi for about 200 NZD, no doubt they are a little slow though.
I guess it all depends on how much you are likely to use it really
