I bought and continued to buy E-Trade on its way down in 2008. The lesson I learned is don't buy a stock that's on fire assuming it probably can't get much worse. Wait for the fire to be absolutely put out and see if there is anything worth salvaging in the ashes. It is from this experience that I feel confident in buying AIG today.
After having dealt with all the major brokerage houses in the last 15 years, I have to say that ETrade's premier account customer service is among the best. They also have a great online user interface for at-a-glance account and tax basis information. They also have a very strong online bond trading platform.The baby in the commercial says so, too.;-)
