I have the ProfiSix with the Profi-flash for about 29 years now and it works great.
The Minolta Flashmeter IV is a bit lighter and more compact than the ProfiSix, but it has a miniature-probe that you can use for table-top.

For fast work the Profi is better because you don't have to interpretet the reading as with the digital Minolta.
Graet stuff and highly recomended.
