I would avoid BA Infospeed DSL at all costs. You've got good chances of being disconnected every other weekend for no apparent reason. Not to sound like an advertisement, but I use acecape dsl because they're reliable. They use BA lines though, so they're not as good as covad, but I haven't had any downtime in 2 months...unlike BA which had given me 3 weeks of downtime in the 5 weeks I was with them.
As for d/l times and latency, it's nearly equal, maybe a little faster now then BA was for me.
[edit]oh, I forgot, acecape has a static ip and no pppoe[/edit]
