Looking for the best flash for Sony A 100 digital camera?

I recently bought a Sony A 100 digital camera, with a 18mm to 70mm lens. Is the Sony HVL – F 36 AM the best flash for this camera? Or would you recommend another I should look at?
I would like to get into taking wedding pictures after I get enough practice.

the 36 is a wee bit low powered and only has bounce, not swivel on the head, you really want to go for the F56 instead.
