I agree, I have both...no wait, I have a IV and a 5000. At the time I bought the IV it made sense to have two tiers of 35mm scanning capability, now with the V priced equal or above equivalent flatbeds, there is no point for it. Five years ago flatbeds could scan prints...and that's pretty much it. I had a slide adapter for an expensive HP flatbed at that time...what a piece of crap!Chris, the difference between scans from the V and 5000 is like day and night! Not even in the same class. The 5000 scans 35mm as well as the 9000!
