I've just been looking at the ringflash adapters that are available from eBay for around £50 (these are the things that attach to a 580EX flash). I know the 'proper' branded items are more like £180 and, to be honest, I've no idea whether even these are any good, let alone the bargain basement eBay version.
I'm generally a big believer in "you get what you pay for", but if I'm not buying a proper macro flash (which at the moment, I'm not) then I'd hate to miss out on a cheaper alternative.
Any ideas on whether these things are any good?
