I have one, but goes with a MKX... Actually, there's a few other dongles, Zero-X for sure with a 3 or 4 cart interface. Pretty much all the Steinberg interfaces, accelerator(s). No video enhancements. But wouldn't let them go without a "full system" $ale.
An MK-1 option exist, with fewer hardware options and roughly half the investment. What that is, is subjective.
