We haven't switch because of the research we've done and what friends have told us. Anytime I've had issues we Insight, which have been few, I'm on the phone with someone from America in a matter of minutes. A friend, who recently switched, has had a few problems and reports long hold times for "overseas" technical support.
The pricing looks good on the surface, but appears to be only temporary. After the first year of service the rates go up to amost exactly what Insight is charging. Insight is constantly advertising low rates for "new" customers.
It's all about getting someone switched over with a low ball rate and then sticking it to them after the switch.
