Re: Yamaha DTX500X...???
You should check out the Roland TD-4K2. I've seen them go on ebay for $560, and that would be way better than the yamaha. You could also check out the Roland TD-3, which is probably more comparable to the yamaha, but you can get them for cheap. I got a used one at Guitar Center for $350, but then sold it for $550, and that's usually about the price range they go for. If you can actually go try out a Yamaha and a Roland that'd be good to see which one feels better to you.
