I think the VMS4 is the only 1 in that price range with 4 channel faders.
Controllers with only 2 faders like the VCI 100 can still be used for 4 decks tho with a bit of midi jiggery pokery altho if you've got decks A & C for example on the left side using the same controls and want to mix between them can be a bit fiddly, if you get me? To get around that problem I mapped my BCD2000 as a rotary style mixer using the 4 knobs across the top as faders and their corresponding buttons as pfl/cue controls.
Thinking about it, I'd just get a good ASIO soundcard for now like an NI Audio2 to get the most out of the Hercules and build up from there when you know the features you're actually using in the software or the features you're struggling to access with the Hercules. Once I got into it I found there is no such thing as an all in 1 controller as different people want to use the software differently, so you'll probably end up buying another controller to add to the setup anyway.
Traktor's waaaay better than VDJ btw
