ShareScope Pro is about £30 a month cheaper than that for a Private Investor and the two packages are fairly comparable.
That's what I use for my stock scanning.
At the moment I use a stock ISA with a brokerage charge of £9.95 per trade, however, I don't have to worry about CGT atm.

SimonK has the best advice I've seen on here.
I prefer 2 screens - 1 for Stock Analysis 1 for broker software and anything else I want running.
However, careful use of alerts,screening and stops and I can't see the problems a lot of you are going on about unless of course you're all madly...
