Ref my earlier post, I had a good look around at what was available for my A200 and was quite surprised at the choice.
By chance I popped into Curry's yesterday and noticed a Sony HVL-F36AM for just £99.97 in their camera cabinet, which is cheaper than anywhere else I've looked at.
I can't see it on there web site though, so it may just be an instore price ?.
Hope this helps anyone else after a decent, but cheap flashgun.
