Given that no hardware controller in the world gives you complete control over a DAW, the best use of your money might be a Touchscreen monitor. I have been using a 27" Acer (about $550) with Studio One that gives me performance on the level (or better) of Slate's Raven at half the cost and without an additional software layer (Studio One has probably the best native touchscreen support among DAWs).
Hardware controllers are, in my opinion, a step backwards at this point of the game. YMMV.
don't get too caught up in technology there.
touchscreens are great for something but just not everything. not to mention they are like "Glass" (excuse the joke)
almost every pro studio out there right now are using hardware controllers. touch are indeed good for something's,
but I do not see hardware as a step back. more controllers are being made today then ever.
digital boards that interface with DAW's is the standard for most pro studios.
touch has its draw backs, for example, to be super accurate, you need gestures/ click +enter.
with a hardware fader in your hand you can dial in much faster.
im not even going in to transport controls either.
to the OP, Mystic38 brings up a good point the x-touch looks to be a nice draw up by Behringer.
like I said before, I haven't always been keen on Behringers stuff but they are improving / using better parts/better engineering.
