Boris, I haven't used Metz 52, but I have been using Metz 58 AF-1 for over 2 years now (probably even 3). Below, I compiled my impressions (posted earlier) of that model. I am not sure if it is anywhat representative, but at least it will give you some aspects that you may want to pay attention to.
>>>>> I find Metz 58 (I have af-1) - considerably better and more flexible than AF540. Two main reasons: 1. It works reasonably well in "A" mode. 2. It has the secondary smaller flash in front that is useful for the situations when you bouncing light off the ceiling. I haven't used all capabilities of that flash, but these features are useful. I only wish I could switch the modes (PTTL <--> A) via a slider/button, as opposed to the menu, and that different modes would keep their settings (say, for the small front secondary flash) separately. - So that I would have it enabled in A mode, but disabled in PTTL. <<<<< > 4.

It's been a year since that comment, and it still works, but I need to pay attention to the position of the hot-shoe. I don't know what type of shoe 52 AF-1 has.

It has touch screen interface and seems to be pretty darn good in terms of functionality/price ratio. Do any of the honored list members have this flash and can share with me their experience?
