That's an excellent price.

With recent bodies, like the K-3, you can set the flash power of the camera manually, and there will be no preflash.
To answer the original question, at that price it's an excellent idea. I used two 500FTZ in my studio for quite a while. The perks are:
-great build quality
-clean interface, fast and easy to control (better than, say, a 540FGZ which has too many features and too few buttons)
-good power, plenty of power adjustments
-optical slave is reliable
-good recharge time
The limitations are:
-auto off cannot be disabled if you use the flash in M mode, with a radio trigger (not a problem in optical slave)
-battery door can be lost if you're not careful, it comes off entirely
-that's about it...
I changed my setup for Godox v850 flashes because I wanted to control settings such as power remotely, and was drawn to the extremely long battery life of the Li-Ion batteries.
