Hi eldiablo,
while reading your post I had this feeling of a deja vu.
I really don't know why...

I did some research on MIDI controllers. I bought an Hercules e2 because I used to work with CD/Vinyl for years and I wanted to see if a controller could make me happy. It did, so I need real controller and not a toy like the e2.
The three controllers I ended up with were the VMS4, reloop Mixage and Denon MC6000. Like Jim said I read a lot about trouble with the soundcard and crappy jog wheels on the VMS4. I already have crappy ones on the e2 - I decided against the VMS4.
I tested a reloop jockey 2 from a friend of mine and it is really solid and worked fine. But personally I miss the VU. The Mixage would be a better choice for me because of the VU.
The best controller I could find (beside the "the-price-hurts" Numark NS7) is the Denon MC6000. It is more expensive than the Mixage, but it looks like nothing is missing.
A few days ago a tough rival to the Mixage appeared: the MixVibes U-Mix Control Pro. I think it plays in the same price range like the Mixage and has everything you need for DVS/Cross (but no VU

)
I don't how much you want to spend for the controller so my advice: have look at NS7, MC6000, Mixage and U-Mix Control Pro, ask yourself what you really need and how much you want to spend.
I will stick to the MC6000.
Cheers
