Beginner Flash for macro photography

[jus_tin]

So... I've recently started getting into macro and need a flash of some sort. My question is will any old bog standard flash be ok since the light will be diffused some how or should I go for a TTL flash? Think I'd prefer a TTL flash but would it still need diffusing??

Have a look at this long thread from the macro forum - dozens of different flash options http://www.talkphotography.co.uk/threads/show-us-your-macro-rig.132158/
