If your looking to get exposure to price movement quickly just get an IG index account and replicate the share purchase using a spread bet. Can be set up in less than an hour provided you don't have an adverse history. No good if you are in for the long term as you'll have to keep rolling contracts but think they offer June 09 contracts on most UK names and the bid-offer is normally quite tight plus its tax free. I've managed to make a few quick bucks in the recent turmoil, but be careful and make sure you put sensible stops orders on.
