I was Googling for someone to laser some acryllic for me, idly typed "laser cutter" into fleabay, price + P&P lowest first...

I found a dinky little laser engraver/cutter with a buy it now of £550 + £45 shipping from Cornwall.

I thought, "What's the worst that can happen?", offered £500 and got it.

You may now tell me what is wrong with it and where I could have bought a new one for less
