Hmm... no serious problem, although if you've just started an IRA (like myself) and have less than $10,000, they charge you an annoying $2.50 per quarter until you're above $10,000. Wouldn't be so annoying except that they take it out of the principal that you invested with them, instead of just sending you a bill. Customer service said "sorry, that's just the way we do it."
Yeah, it's $10/year, and it's not all that much, but it's the principle of the thing, dangit.
Other than that, and if you don't have to deal with the annoying people on the phone... fine so far. And nice to know that they weren't implicated in lots of the market-timing/after-hours trades that some other houses were cought up in.
