Depends what you are going to be doing with the Golf?
At £1k you are into much higher end suspension, personally I would say well past decent - but the investment would be worth it if your are keeping the car for a while our planning to go on track days.
If you are just looking for good suspension for daily use I would recommend AP coilovers that I run on my Gti.
Current price is £480 - they are decent with a firmer OEM feel.
