Samsung SEF-54PZF Flash

This is the Samsung branded version of the Pentax 540 flash. I picked it up from here a few months ago. It's in good condition, but with no extra accessories. The Pentax 540 manual can be downloaded and the functionality of the two units is identical (I've also got the Pentax version and could find absolutely no difference between them apart from the labelling).

I'm looking for £170 including UK delivery

Any interest/offers? Could have it packed up and in the post for tomorrow
