Darren,
Welcome !
Any of the traditional breeds will do well for you - and all enthusiasts will tell you that their breed is best, gentlest, friendlyest, most fun/best eating etc.etc

For ourselves, Saddlebacks are good, GOS are also a nice pig, as are berkshires. Oxford Sandy and Blacks are very pretty, Middlewhites have character and are smaller, and Kune Kunes smaller still. I will now be attacked for ignoring other breeds, and would not want to put you off them.
Do your research, and if you can see some great !
Good Luck
