TD Waterhouse has been fine for us. However, my wife and I make only a small handful of purchases a year at best.Most of the posts about discount brokerages revolve around costs. There is very little discussion about the reliability of the web site. Low fees are fine only if you have access to the market.
RBC Direct has been having their share of problems lately with the site or portion of it being unavailable twice this week. It seems that this has been a weekly occurrence.
Please share your experiences with your discount broker.
