Is any LiDE scanner acceptable, are there particular models that are recommended ?
I think any Lide is model ok.; apparently what makes it good is the fact it has an LED light source.
I don't have a Lide but an older Canon 8400F. I nearly abandoned it when I went to W7-64 bit last year, but thanks to the new 64 bit version of Vuescan, that enabled all the scanner features to work with the Canon 64 bit driver. I think Vuescan is essential with any Canon scanner unless their software has improved recently - you wont regret using Vuescan.
