i have a pair of the wrecking machines and I love em. I crank em up pretty fast for my style, but they dont give me any problems. they are a versatile enough machine that you can run em at real ow volts for smooth shading, and crank them up for solid color. I cant say enough good things about those machines. they are great for someone with a fast hand...and the cutback shader does much smoother blending than any of my more "traditional" machines.
