There has been a number of threads regarding prop guards.
I started one myself as also I wanted to protect my childrens toes. The genreal answer was that propguards reduce power and speed, and if your/my children are anywhere near the prop then it should be turned off anyway.
But if you decide you need one anyway, steel developments had one on thier stand at RIBEX, and I know that it is available in different sizes, so it may be worth giving them a try.
Its all got to go - make me an offer...............
