I have both the DFX and V3i and love both machines. The graphic display and operator information is fantastic with the V3i. If you like to tweak the settings purchase a V3i, you will not be disappointed. I find my DFX an excellent machine and enjoy using it in the field, with less settings it may appeal to a larger group of people. Both machines have a learning curve, but once you get the hang of it, they are basically a turn-on-an go detector.
