The DB2 is pretty good, It's pretty much an all round workhorse for all things music related. The biggest plus I reckon is it's inbuilt sound card and effects component. There both top notch in my eyes and ears more importantly, and make a great addition to people doing both producing and dj'ing. The ability to chain effects on tracks whilst in the production process before you decide to use specialist plug in's is too me a great improvement to workflow as there are so many too choose from within an arms reach. You can also send them to a return channel on your DAW of choice and use that instead if you prefer. Also using the midi mode is a really convenient way to control knobs and what not on any vst you may have, I personally like using them for soft synths as it can get tiresome playing around with the mouse. It goes on and on.... I pretty much read the manual a couple times before deciding to purchase it just to be sure, and I'm glad I did since it does what it does so well. I reckon you should go for a DB of any series, but if your considering the DB4 then go for it. DB4 is a serious workhorse, It's pretty much on its own level in terms of functionality and quality. I was considering the Xone 92 as well for the sheer fact it has 4 band eq, but the inbuilt soundcard and effects on the DB2 were too good to pass up.
