Re: Is it crazy for a beginner to get the DTX700?
The way I see it, if your budget permits it, find out what has the best pads and go for that.
In my opinion, with electronic drums, the closer you can get to the feeling of playing an acoustic kit, the better. And that can be very expensive.
I don't know that model but, as a beginner, forget about how many input and output ports it has and make sure that pads and processor are good enough to give you the feeling of playing a real drumset.
If that gets expensive and you can afford it, then go for it.
That's just my 2 cents thoug.
