I own a DN-S5000 and its a seriously awesome piece of gear.
There are a couple of nagging issues with it however:
-Its not the industry standard, so if you want to use it, bring it with you to the club (kind of annoying)
-Look at it, there's ALOT of buttons. Definetly read the manual, you will thank yourself later.
-It gets better, the Denon is SO feature loaded that many of the buttons are actually menu buttons (keep hitting the button to cycle through options), so getting to something you need might not be as easy and intuitive as you'd think.
Honestly tho, other than its overt complexity there's really nothing to fault it on, if you have the platter bit with the disc properly set up and tightened it kinda feels like an old 7" 45rpm on a belt drive turntable (except super responsive) and you can scratch, backspin...the works.
I own one and I love it, the whole mixing 2 tracks off the same disk is really cool (once you get used to the controls, you use a dail as the pitch adjust on the alpha track) and presents some interesting possibilities (have accapella synths or vocals to loop over tunes on the same cd etc).
But I will definetly say that its not for everyone, don't bother if you're not really interested in all the effects and sampling options, as the whole cd-turntable thing is done just as well by Numark, Pioneer and Technics. Denon just has them beat on features, easily upgradable hardware and alpha tracking (but you can get the DN-S3000, which is basically the same thing as the 5000 minus the alpha track).
Sorry, I rambled :lol:
