I am looking for my first flash, but I can't decide which one to buy..
I would like to shoot weddings and important events.
Later I would like to have a better flash of course, I know one flash is not enough, but I would like to buy my first flash.
I don't really want to buy a bad one, so...
Metz MB 50 AF-1
Metz MB 58 AF-2
Canon Speedlite 430 EX II
Canon Speedlite 580 EX II

Can somebody help me?

Thanks in advance!

If you're willing to look into non Canon brand ones, check out the Neewer full manual flash on Amazon. It's like $50.

I don't want to get a bad one, would like to have a good one for long time, but thank you!

It's not a bad one, it's a full manual budget photographers flash. I've had mine for quite a while, it's very nice.

Uhm well, I meant I need a really good one for a long time, not so cheap, and I think I will buy the 580 EX II

I guess I don't know your definition of good then, it is a good flash. It's just cheap priced because it's full manual. The 580 EX II is a good choice though.

I meant, I will shoot weddings/important events and I don't want to buy an untrusthworthy flash, if you know what I mean.

Oh...
Trying to buy the 580ex II but as I have seen in the shopsit does not offer one.. shall I buy the 600EX R-T?
Does it worth the more money?

just bought the 600ex-RT, works very well

excellent flash

but yeah the "cheap" 1 he was mentioning would be the Yongnuo
i have 3x YN-560ii (fully manual), great flash, never had a problem, recycle times are awesome, happy with quality build etc etc
if u want a ttl flash they have the YN-565ex, again i have used it extensively and its great
if money was no option then yeah i would have a few 600ex's and a high end metz but its not worth it for me, can do everything i need and more with what i have, the money that i would save would rather go to extra units and modifiers
