Re: Want to buy an electronic kit - but I don't know where to start!
I don't know of any set that comes with all mesh pads that you could get for so cheap. If all you wanted was a mesh snare, then it'd be possible. So what I would recommend is either buying all the pieces separately, or buying a complete set and then upgrading or downgrading. Like if you bought a Roland TD-3, sell the rubber pads and buy mesh. Or a TD-4KX and sell the extra pad, or a Roland TD-9, sell the extra pad, sell the module and buy a cheaper module. I still think all of these will put you a little over $600 though.
Roland is the best for mesh pads, well they're the best in general, but because of that they're a little more expensive. I know Alesis has cheaper sets and their sets don't come with mesh pads, but you can buy just the mesh head to replace the one it comes with, but I don't know if that's possible on all their sets or just the more expensive ones.
