perhaps I need to clarify.

Buying the most expensive/best quality item is not always the answer. I have a friend who does that, and he burns cash like its going out of fashion, which I cant do, despite what people might think.

Its got to be value for money, which is what we all want regardless of what you buy. Value is of course an unmeasureable, personal, qualatative process.

What I mean by all this is
When im looking at an item, i decide what i plan to do with it, my constraints, and then look at cost last. If I have to spend the cash to get what is the best option for me, then thats the way it will be, but if I can satisfy my needs with a cheaper model, then why put your hard erned cash into someone elses pocket.

With that in mind, i havent heard of Fronius. ill have to do some research on them and have a look at what they offer and the average cost.
