AVC sell an Astra product, Micronet a Eutelsat/Opensky, in fact is there aren't any companies like this I know of that can afford to have their own satellite to do everything themselves.
I do use the AVC service myself, and I use it even though I have a 512Kb/sec ADSL line, as it provides me with a more stable, and quicker download - rarely dropping below 100KB/Sec, and mostly above. (I use a 1Mbit/s connection)
I have only met 5 unsatisfied customers (out of over 200 I have dealt with), these were all due to equipment failures (tuner blowing in the receiver), but there are always some, and am installing more every day. Most of these people are having it installed on recommendation from other customers - not from advertising.
People don't recommend a rubbish service to their friends or neighbours, and there are people in my area that I recommended it to who use it with no problems and think it's great.
Because the dish is used for Sky too, they have to use Sky registered installers, or else within the first 12Months of a Sky installation the systems' warranty is invalidated if the dish is modified/changed by someone who isn't.
Unlike Micronet, I am not a rep, agent or reseller of AVC's product. I am an end-user who liked the system, Install Sky for a living, and now I install AVC Broadband in certain areas of the country, as they were looking for installers.
AVC Broadband doesn't need self-praise from a rep.
