if they are available where you are you might like to have look at aliebees as they  are at reasonable prices and said to be efficient source of light http://www.alienbees.com/

can't say i have heard about those lights, but i second the vote for alien bees if you live in North America.

Forget Amvona, go for the Alien Bees.
Also, 300 Ws is not nearly enough power.

I have lots of Amvoa stuff that I got off Ebay for VERY cheap: reflectors, tripods, heads, muslins, softboxes.... I've had some of the stuff for over 3 years and they still work great. They're NOT top quality but they get the job done.

When I saw their flashes on Ebay I decided to give them a try. I got http://www.amvona.com/?page=shop/flypage&view=1&product_id=3189 for onyl $305! That covers the cost of the softbox and umbrella. :-)

Verdict: For the price I paid I got a really sweet deal! The tripods are solid but the springs feel loose. The 300W strobes work fine and recharge faster than I would of thought. 300W is more than enough power for studio work. I also have three 400W Aurora Genesis strobes (which cost $650 each) and I rarely go over 1/2 power. The softbox in the kit is well made like the other 3 softboxes that I already have from them (I got a lovely 5ft hexagonal for $65!).  The case is solid, on the heavy side but with wheels, and well padded. It also comes with a wireless remote which I haven't tested because I already have mine. I have to say that I've only had the strobes for a few weeks now and I don't know how long they'll last but for that price who cares. I see it as having bought a nice cary case , a softbox and an umbrella and the strobes were free.   

Haven't bought lights yet, but the set kosmikkreeper bought shown at link http://www.amvona.com/?page=shop/flypage&view=1&product_id=3189 retailed for 780. The alienbees digital set at http://alienbees.com/digi.html retails for about $700. It is essentially the same kit at 400w.

Couldn't find much in the way of Bees on ebay, which may say something in itself.
