Thanks for all of your replies gents (and ladies?).
This place really is the fountain of all knowledge!
Troddenmasses, will nip over at some point and get a few lessons from you and keep my eye out for some cheap kit (though on reflection space is a bit of an issue at the moment, shed is rammed with summer kids toys).
Thanks again everyone,
Keith
