Anyone with much experience with the Mini Q-tron? I have an original Q-tron, and love it. I also have a 3leaf Proton that I love. I'm a bit of a filter whore and my love for my q-tron is getting me thinking a mini would be cool. Would a Mini Q-tron give me anything I can't get from my Proton or could it replace the proton or the Qtron?
