ML is on the money - all depends on budget mate, if money is no object I'd be looking at the Canon 580 (mk2?) or the 430 - but the YN 565 at $150 gets good reviews for a cheaper flash. I'm pretty new too and that is what was recommended for me. The older/less powerful YN models go for a lot less, well under the hundred dollar mark but I'm no expert. I've been told the 565YN does what the Canon 580 does, but it can't act as a "master", only "slave" - also from memory no HSS capabilities. BUT it's a hell of a lot cheaper.
