Cracking bit of kit (according to the research i've done!) best type of stabilizer around, doesn't try and control the shake, it stops it from starting in the first place.
Looked at a few old ads and they seem to go for around £55 second hand, so how does £60 for a brand new one sound? If you need it posted hdnl should be able to take it for under a tenner.
ps, you aren't supposed to fit these to s-reg and onward cars.
