Funny that, i seem to remember something about that also
Seriousley though, nice piccies, and i want to try some myself there.
Nikon or Canon are both good makes, i use Nikon because it's what i have done for a long time, you buy a few lenses, and then you are tied to that system [unless you don't mind losing a load of dosh changing makes]
But i'm used to Nikon now, Nikon D80, or Canon 30D, both excellent capable cameras, and an outfit of either, lightly used will be within the £500.00 mark, with some bits and bobs thrown in, enjoy.
