Hmm can't say I agree on any of that. I don't know about BCD3000 because I have never bought a jogwheel midi controller. However they the VCI-100 is an amazing controller and comes with a built in soundcard so you get nice low latency and a headphone cue socket.
Decks are not for all. Some people don't want to beatmatch by hand and would rather worry about mixing and effects. Midi controllers will be the way forward and that's obvious as Pioneer have brought out new CDJs and so are Numark. Traktor comes with a soundcard with most of it's bundles. Traktor is and in every way better than Virtual DJ. I have never and hope to never see a DJ in a club use VDJ. Look at all the videos of DJs and Scratch DJs on Youtube and they will only be using Serato (same price as Traktor) or Traktor. Serato and Traktor Vinyl will work with some software. It will work with Mixx and XWax and other software. However Serato and Traktor would rather that you couldn't use the timecode vinyl with other software. That you can only use Serato if you own Serato approved hardware or have their soundcard. Traktor is the exception because you pay for the software were Serato is "free".
I can honestly say that with DJing brand names mean everything. Pioneer decks are the industry standard. In the US Serato is the popular choice for timecodes and in Europe it's Traktor. You only need to look at screenshots to see that Traktor and Serato have a much more friendly and easy to use interface than something like VDJ.
If you read on DJTT forums most newcomers will buy a jogwheel midi device and work their way up from there. However you may find that you are just fine with a controller and may want to spend any extra cash on some side controllers or a new soundcard. Decks take up space, cost money and you have to buy a mixer. While this can work out cheap, you don't get quality and in the end what's the point.
BCD3000 feels like a childs toy, believe me, plus most brands midi controllers have a built in soundcard, as for what you say about brand names being everything!! how? they mean nothing, industry standard means industry standard, not the best, if you have plans to play in clubs and be a professional hired club dj then you will need to learn and buy traktor/serato and pioneer/technics, as this will be the equipment you will use, and your straight in at the deep end with no tutorial, as for quality of sound, that is only ever as good as your needle, mixer and speakers, cdjs are digital, end of.
you wont see virtual dj in a club as its not club standard, its for djs who tour and do parties and stuff, how you think traktor or serato are any different is beyond me, ive used all 3, and they all do the same thing with a different skin basically, please dont tell me what you read on a forum, it means nothing without personal experience, not knocking you, if you want to believe brand hype its your money
Whatever you buy, the mixer is the single most important piece, if you want cdj, its upto you if you want to spend 2 grand on pio's flagship decks, however denon make equally as good midi/cdjs, and are cheaper, even numarks new deck is very tight and well worth checking out, regardless of your brands of choice, mixing is mixing and if you are not beatmatching manually and cant do it using a platter and pitch slider then you are going to be in big trouble trying to use other equipment, when you can do this easily within 4 bars then it makes absolutely no difference what kit you use as all you need is play and stop. Loops, effects etc are luxuries and really only used by trance djs
