Lite Canon anytime. They come in rechargeable or non recharable models. Get the non rechargable (which is about 60 quid cheaper) then buy yourself a set of Nickel Hydride batteries and a fast battery charger. Two plus points, you save youself some money and you don't get lumbered with the crap NiCad battery that comes with the rechargeable model. If your looking for something a bit cheaper why not try a good British made Birchley (my mate had a YL years ago and it blew my old UK600 out the water)
