>>2917198I use a 7400, it works pretty well. I only shoot B&W so I couldn't use IR dust removal anyway. Also the newer 8100/8200 models are the exact same hardware as the 7400/7600 just bundled with newer software, but the software is shit and you should ditch it for vuescan anyway.
I think the image quality from the 7200 should be about the same, but it doesn't have an LED lamp like the newer models so it has to warm up when you turn it on. Try to find a 7400 or something newer instead, I got mine used and dirt cheap.
