Looking for a new detector: f75, V3i or E-Trac??

I know this is a hot topic but I'd like to hear it again lol. I've been using the DFX for a few years and I love it but recently I am feeling the need to buy another machine. I've narrowed my choices to White's V3i, the Minelab E-trac or the Fisher f75. I guess I would like to hear some opinions from people who have used these machines. I am most interested in the machine that has the best depth. I am partial to the whites because I have always had one but I am not so impressed with the reviews of the v3 compared to the DFX. I like what I hear about the F75 but it sounds like an unstable machine. As far as the e-trac, I do not hear too many bad things so its at the top of the list right now. Love to know what everyone thinks. Thanks and HH.
