I spend about £1000 a year shooting the SWEFTA league shoots and the closest 6 GP's But in comparison with these other sports that still works out cheap. And as said earlier, good FT kit holds it's price.
I saw an S400 with a 32mag scope sell for £300 the other day. You could buy a new top of the range Anshutz and an 80mag March with a combined price tag of nearly £10,000 but you wouldn't gain much more than a better trigger and a more adjustable stock.
