Reply to 4 Channel Mixer

So after getting a solid set up with midi controllers, i'm looking to get into CDJ and mixer DJing.
I've been looking around for a prime 4 channel mixer to start with 2 cdjs, and then buy 2 more later.

I was highly considering the Behringer Nox606 but i hear that it's a pretty low quality piece of gear.
Then i was looking into the Behringer DJX750, but it's still behringer with their reputation of not high quality.
The Denon DNX1100 looked pretty good, extremely basic and simple, but perhaps a bit empty?
Then I found the Mackie D4, which looks amazing, but I'd be amazed if I could get my hands on one of those.

Of course allen & heath or pioneer mixers are really nice, and i really love the Vestax PMC-580, but those are all pretty pricey.

As of now, I don't have a very big budget, so i'd like to spend not more than $500 on a 4 channel mixer.
Suggestions? Comments?

I'd really like something with LED volume indicators for each channel, that is the key feature i'm searching for.
