Wanting to put a stunt cage on my cbr600f3 but im in the UK. the forstunt cages are really cheap at £70 compared to £190 for the 905 cage...anyone got a forstunt cage who knows if they are any good?

bike owes me very little so dont want to fork out loads for a crash cage that will cost half the bikes worth so need a cage as cheap as possible hence looking at forstunt.pl website
