I spent years with 5 people on 12mbit ADSL2. I'd rather have that than virgin and blocking any day. I suffered Virgin for a couple of years and it was hell.
Now I'm on ~64mbit VDSL with no blocking at all on Zen. We pull 500G+ a month through it. Costs £37.49 a month.
They just rolled out 300mbit fibre as well so that's going in next month.
Speed isn't everything for me. I can QoS those problems away pretty well.
