Burlbark, you are quite correct about the "magic bullet". If someone is looking for that, they might as well try cornering the genuine Easter Bunny.
I have a new Spectra VX3 on the way. I might be selling my Equinox 600 soon, along with the 6 inch coil and an extra lower rod + a pair of Paww Wavesound 2.1 Wireless headphones (works great and is low latency). Just don't know yet, but wife says I can't keep em both(too much of my stuff already hanging around).
It will take you a year to LEARN V3i. It's heavy, and overpriced. The MX Sport is a, well, it's not worth the money. Stay away from Whites. Good Luck!
