Re: V-Drum Hardware (throne, pedals, hi-hat stand, etc)
I picked up a DW3000 series double pedal and I love it. There are more adjustments on it than I know what to do with. It's honestly up to how much you're willing to spend.
As for your choice of Roland TD15... dont count out the stuff that Yamaha is making. You're selling yourself short if you don't at least check it out.
