Re: Roland vs Yamaha vs Alesis?
From past experience with all Alesis products (that are not being hit with sticks) I would stick with either Roland or Yamaha. Some Alesis products I've used were not built robust enough and had issues over time. I can only imagine what would happen if it was now being beaten daily with sticks.
Of Roland or Yamaha, I've personally owned the Roland V-Drum TD10 kit and loved it (back when it was the flagship of the series), so I'm biased towards Roland. But lots of people think the Yamaha stuff is great too.
