I'm with Tiscali too and have been happy for the past 2 years or so....
One thing I would be wary of is their MAX package. On this you get up to 8meg, but what they don't tell you is that customers on the MAX package get whatever bandwidth is left after everone else has had theirs. At 2.00am it is very fast, but in the evening it is much slower than their standard package. But you can easily switch between them, so if it doesn't work for you, you can get back on to the standard package.
