Hi Eircomnet,
For the moment I'm doing nothing and letting Goodbody hold my shares in a nominee account. I only have a small amount of shares with them so am not overly concerned. If I had my life savings with them it would be another matter. In any case, Goodbody is a wholly-owned subsidiary of AIB so it is fairly unlikely it will fold (but not entirely impossible).
AFAIK Sharewatch offer a Crest account and also have much more competitive comission rates, but I don't know what markets they deal with or how quickly they execute trades. I've never dealt with them myself but here is a link if your interested in reading about them.
