Engine mount price?

[rtha6551]

My gearstick in my HDi wobbles when coming off the throttle most noticeably in 4th, from what I understand this is the (top?) engine mount?

Not exactly sure what I should be searching in eBay etc? What I've found range from £30 to £150!

If someone could post a link of what it is that I need and how much fitting should be then that'd be much appreciated

Thanks
