For Canon users on a budget these guns will do just about everything that Canon's flagship gun will do but at about half the price - you can pick these up for about £165 in the UK. The build quality isn't up to a Canon and the userface is a little complicated to start with but like most things you get used to it after a while. The exposures are consistant and very nicely balanced. For anyone who is starting into using strobes both on and off camera I believe these offer much better value for money than any other that I have seen. Add to this that they now come in all sorts of 'flavours' (Canon, Nikon, Sony, Pentax and Sigma) these flashes certainly warrant some serious consideration at least.
