Mr Scan looks promising. Possibly worth it for APS film especially as I do not have to deal with opening up the APS cartridge. At the lower end for 35mm slides but it still adds up if you have a lot of slides. Probably better quality than the "scanner"* I bought, but that job's already done and I can always rescan those I am not happy with.

I bought this scanner. You can also read my review of it there. The other review dismissed it completely. I didn't think it that bad and I think it is a matter of expectations. If you want perfection, then these devices are not for you.
