How can I find a list of self-select stocks & shares ISA providers? 
http://www.moneysupermarket.com/shares/CompareSharesForm.asp lists many. I found the Interactive Investor website to be excruciatingly bad. I switched to TD Waterhouse and found the website good but the telephone service a bit abrupt. I often use the data presented on SelfTrade but don't have an account there.
