Hi Nick, I'm glad to know you're not feeling wishiewashie about this!
:-)
Seriously, when were you last a Waterhouse customer?
I don't know much about Scottrade. In the past some of the deep discounters didn't pay interest on cash holdings and charged extra for Limit Orders and such. So, the Service VS Cost question seemed to favor the regular discounters.
Please feel free to tell more about Scott Trade as it might be timely if Waterhouse does change their facility/interface to something less desirable.
Best regards, Tom
