Personally on my house system, I use 2 supplied with modem SpeedTouch filters and Ebuyer cheapest. Been on my system now for a number of years, and never had a problem or failure, so I could perhaps suggest that the dearest may not always are the best!.
Who knows whether this is correct or not but I am inclined to disagree from my own experience. As I mentioned earlier I had a Speedtouch which despite working perfectly well on fixed half/one and two Meg was not up dealing with ADSL Max up to 8 Meg.
wee eddie - No disrespect intended but if you are only paying a fiver for them then that might be your problem :)
The one I referred to can be bought from click here cheaper than ADSL Nation themselves. £8.49 delivered doesn't break the bank.
There are, IIRC, a couple of different designs at least for microfilters/splitters - one is reckoned to be better than the other.
The only time I've had a problem with one (those that I have come from either Tiscali or TalkTalk) was when the other half, thrashing the carpet with the Sebo vacuum cleaner, caught and turned the front of the microfilter through 90 degrees.
I Sellotaped it up temporarily, but still haven't actually replaced it some 14 months later...:-)
My 25 per cent level of Scottish blood decreeds that if something is working, leave it alone/don't buy a replacement.
