Ross: Have you looked at the Quantuum R+ 600Ws dual power unit?
Two links for you (same vendor, different target markets) :-
http://www.ebay.co.uk …n_212&hash=item2a12895787 - priced in Zloty (about 21p)
http://www.ebay.co.uk …in_77&hash=item5aec175689 - priced in Euros (about 85p)
You'll have to translate from either Polish or German to read the blurb! Notice the price difference (and then notice again the PayPal conversion rate, very beneficial ...... to PayPal). You also get to play the interesting Exchange Rate game; which can occasionally work out to your advantage.
These are basically rebadged Mettle units, which several folks here are using successfully. But then again, the Lencarta are rebadged (and tweaked, they insist [no personal knowledge of this]) Jinbei with the exception of their forthcoming Ultra-fast duo which are Godox.
Salient features, perhaps not readily apparent in translation:
- NO import duty or VAT because they're already in the EU.
- TWO years warranty as required by EU law.
- Reliable reseller - I've dealt with Hubert several times and he's quick and accurate.
- Bowens-mount accessories - the most readily available mount worldwide (aka the most copied!)
The rest of the research I shall leave to you!
