I was rather surprised to see how cheap these things are. How dangerous are these gadgets? Anyone had any nasty experiences? I'm a bit worried about screwing the engine, especially cos it voids my warranty.

Tony these things are only really dangerous if you turn the boost up to far, or that your car runs lean and/or spikes at high speed because of it.

That is why it is important to fit an AFR ad a boost gauge in conjunction with a boost control.

As ever common sense prevails.
