rear diff mounting cost, need help

Got to change all of my rear diff mounts, I found one in ebay (from qualitypart) selling those parts for just £51 including VAT and postage. LAND ROVER FREELANDER REAR DIFF MOUNTING KIT on eBay, also, Land Rover, Car Parts, Cars, Parts Vehicles (end time 04-Mar-08 12:35:52 GMT)
Now, I'm a bit hesitant to buy this one 'coz its a lot cheaper than in other dealers that i have searched on. i.e. Your LIVEQuote

What do you think guys? Should I buy the parts from ebay? Have anyone tried buying from that seller? How was it?

THANKS A LOT

Dont bother buying after market crap it is nothing but hassle ive bought the front mount off land on saturday for £12 pound thats the bush and the casing dirt cheap or what?
