Thanks everyone for the information and your opinions of film choices.

I have some 30 glass slides waiting at my front door as we speak. Will look at getting some more too.

Hatchetman, I want to address you use of Kodak films specifically here. For the most part, I have always used Kodak films in all my 35mm and 120 cameras. Recently, given the problems with Kodak and reading about some shortages, I am almost afraid to fall in love with Ektachrome just to have the rug pulled from under my feet.....silly thinking?? (I think I have around 3 rolls of Ektachrome in the fridge, I need to get the camera out!).
