Better off buying from world-of-sat who are official distrubutors. Depending on your location you may pay £5 extra for postage over the eBay ad but you're also buying from a reputable company. Not a random ebay user.

All the way from the UK, I guess if you're from around the area. I also bought mine from eBay, but from Canada for $5 more than that one.

Edit: Nevermind, mine was cheaper. $129 shipped from Canada after exchange rate.
