The quality issues all seem to be linked to a capacitor, but apparently it can be replaced very easily should it fail outside of warranty, the actual physical build is top notch.
I bought mine from Photo Gadget, because they have a good rep on PoTN, I'd avoid anywhere that doesn't offer a 12 month warranty. If mine goes wrong I'll have to ship it back to China, which isn't ideal, but they seem to have a good returns policy which is the main thing.
I have a stand, clamp, umbrella and gels arriving this week too, I've spent a grand total of 130quid on a "starter" strobist setup that I can also use for "normal" flash work, can't really argue with that
