... I suspect there's a bit of bikey snobbery with these £500+ shock absorbers going on
I think with suspension you do sort of get what you pay for, and if you want it and need it then you can justify the cost of Ohlins, etc. But if your needs can be satisfied with something half the price, then that's great. I don't think it's necessarily snobbery to want the best, but not everybody needs it.
