HA!!!!! does this sound familiar

I've been looking at the same thing.
First decision is what quality you want and what the end product will be used for.
If you want any type of quality at all, avoid the scanners that just a magnifying mirror to copy the slide. An actual transparency adaptor will give you moderate quality that can be used to store slides and use the images for limited reproductions.
To get "slide" like quality you'll have to opt for a stand alone slide copier (I'm researching prices/quality/options right now).
A decent scanner with transparency adapter will run at least 299. The Epson 1200U has a good reputation but even their techs will tell you to go for the stand alone for high quality copies. HP is supposed to have 2 mid priced models, but the lower priced models will use the mirror system.
hope this helps.
