I've been using a Microtek i900 flatbed scanner for a month or so now. It has a transparency drawer that handles pretty much everything. It does a fantastic job for what I use it for which is proofing and putting stuff on the web. It has glassless film carriers for 35mm strips, 6cm, and 4x5. anything bigger than that it has a glass carrier that will hold anything else up to 8x10 (I think). I really like the no glass scanning: no neuton rings, and a lot less dust. The only gripe I have is that the med format carrier requires that you cut the negs into individual frames. This makes darkroom printing a pain for me, so I've been using my MF film strips on the glass carrier (but I'm getting rings and dust!).
