Real Welsboy as has already been said just ask Barclays to open a nominee account on line then you can buy and sell any time you like without certificates to worry about. Again as has been stated it's also cheaper.
One share you might consider in 2005 is ARK but DYOR first as always. Not on most peoples radar's yet but should be shortly.
A further shot at CS. could of course pay dividends at this price and looking to add again myself.
