Price is a weird sort of thing anyway - going off at a tangent, how is it that a pukka shock absorber for my mountain bike would cost me around 300 quid, but for the same price, I could have four top quality car shock absorbers and a set of top notch, progressive springs? I know some of it's economies of scale, but it seems a bit mad to me. I'm not saying that expensive things are a rip off or that quality is or isn't related to price - sometimes it is, sometimes not - just that what determines pricing levels is so variable.
My advice, if you want to save money, is not to over specify kit. You see lots of people wearing expedition jackets to walk in the Lakes for example. Nothing wrong with that, but you pay more for a load of features you'll probably never use, a bit like going to Sainsbury in a souped-up Ferrari when all you need is a Ford Fiesta, if that makes any sense.
