Sell everything and get MOTU, something like 828 — it'll have all your needs covered for years to come.
I have no experience with Mk3, but previous iterations were great cards.

@newt
I'm sure, the card you posted has 8-10 outputs and 2-4 inputs on the back side too, but cabling doesn't have to be messy, it all usually goes behind the desk and if you arrange it well, it doesn't look that bad.
But yeah, MOTU cards indeed look rather utilitarian — but they are sturdy, can survive pretty harsh trips.
