Thanks angelofsky for a quick reply, I don't mind about the HD at the mo because I will be using the Tuner for my Dream 500 or my iPhone HD don't work on them anyway, been looking eBay and site like that but there are so many DVBS tuners I just don't know which one to go for, mainly the cheapest that works and a loop through option so I don't have to wire another cable from the LNB.
the price I have seen goes from €10 any where up to €200
