Depends on you budget really. You've got Hagon and Hyperpro at the budget end then Nitron/Wilbers offer their budget spec shocks sort of in the middle then the likes of Maxton and Ohlins etc at the £600 -1000 top end. Nitron, Wilbers and Maxton and others offer higher spec versions with custom setups which can push the price up to nearly that.
I can only comment on the Ohlins really which made a big improvement to mine, but I didn't pay full price for it, so it probably wouldn't have been such good value in terms of improvement if I had done.
I don't know if this is of interest, it seems a reasonable budget option?
