If youre only scanning 35mm, should be able to get a good model for less than 400 USD
But if you need one for roll film or larger then it will likely be more in the 1000-1500 USD range. I believe Voodoo has a Minolta 35mm model and is happy with it
I have been personally looking at the Microtek 1800tf, it is a multiple format film and flatbed scanner, its a little expensive 1130 USD
