yep defo go for the microsoft one much better all round.
Be careful if u buy of ebay as sum of the early ones to be made had a problem of over heating and microsoft offered free retrofits on them but there could still be some around that havent had the retrofit.
If u do go for a bargin on ebay look up the sku numbers on microsoft page to find which needed the fit and ask the seller what the sku is under the wheel base otherwise you might end up waiting a few weeks for microsoft to ship it back and forth.
