I have pacbell and for the most part, they offer good reliable service. I was one of the lucky ones to have signed up early on and recieved my own static ip. Sync will drop about once every 2 months... I think it's really a hit and miss thing with pacbell. Some will hate it, and some wont.
And yes, capping usenet to 128kps SUCKS ASS!!!!!!!!!!!!! They cite more reliable service. What a load of crap.
