I have several different scanners,I started with Microtek many years ago,my largest scanner is an Microtek 9600XL which will scan 11"x17" which is about the size of a newspaper page these days.It has the transparency adapter which will allow you to scan film and slides,basically the scanner cover is the light source and you can fill the bed with slides and batch scan them while you tend to other things.
I have had HP scanners,I now have a Canon which does not impress me too much.My latest aquisition is an Epson which I like.I am trying to get the film holders for it and it also has the transparency adapter in the lid like the Microteks have.I think that it may be the best scanner I have for pics and film but have not spent a lot of time with it.
I also have a dedicated slide/film scanner which will also batch scan the whole roll of film once you get it configured for brightness,contrast etc.Scanning is a slow process and the ability to batch scan helps a lot because you don't need to tend to it while it works.
The one common denominator with my scanning is my scanning software.I use Vuescan and it gives you a lot more control over the scanning process.If I had old film and pictures to scan it would be my first purchase.I scanned all of my old military pics before I found out about it and really should do them all again.Vuescan will work with thousands of scanners and Ed Hamrick updates it daily.You can download it from hamrick.com and it is a fully functional trial copy which you can use forever if you can live with the watermark on your scans.When you register it the watermark goes away of course.
You can buy some fantastic scanners on ebay for very little money,I would not buy new without a good reason.Ron G
