Neither tbh. GSF/VWSpares/Volksbits/TPS are the best bet if the dealers are too expensive. Unless the seller on ebay is a decent one (tierod is good), you will get a crap one and that will probably go within a couple of months. ECP have a reputation of giving you the wrong part, especially if you have it delivered, and they have very poor customer services. You could get used one from ebay (I got one and its good if you need to confirm thats your problem), but it may not last very long also.
