Do you really want to bother with Analogue TV? Personally, especially when viewed on a decent monitor i find analogue to be very poor, i have an Elgato Hybrid (which is the HVR900) and only ever use it in DVB-T mode. I bought the WinTV-Nova-TD to make use of the dual digital tuner and its great.
The 950 is aimed at US Analogue Cable users, the 900 on the UK site also claims to come with the Elgato EyeTV Lite package for mac users, ive no clue what the "Lite" package contains, but the full EyeTV suite really is worth the money, it really is a great EPG, interface and exporting suite.
Another device im currently waiting for is the Elgato 310... this is a DVB-S reciever and will give access to the FreesatHD channels, as well as all the other FTA/FTV satellite channels.
