They're jealous because he got to drink out of those cool glasses with the elliptical tops.
For the OP:
A modern top-of-the-line flash in some situations is perhaps going to facilitate good photos more quickly and easily than would a less full-featured or obsolete model, but for run-of-the-mill situations flashes got as good as they need to get about 30 years ago. In the final analysis, they all perform the same basic function, which is to provide a measured output of light. No matter what they cost, how many buttons, functions, modes, etc they have.....that's all any of them do. And so long as they do that accurately and reliably they meet the minimum requirements of a flash unit. They're sort of like a pair of eyeglasses, if I may be excused a weak analogy: Upgrading to more expensive frames isn't going to improve how well you can see through them. Once the prescription matches your eyes, the rest is superfluous.
A few examples from a $10 flash and a $15 lens, with setup shots first:
All
Pentax K20D
SMC Takumar 55/1.8
The flash is a simple AF200T that Pentax put out sometime back in the 1970s or 1980s and which I picked up from an auction for a whopping ten whole bucks. Could I take the same photos with a brand-new 540? Of course I could. But I don't have the money for 540 and I don't shoot any situations that would benefit from the extra capabilities it has. If I
needed those capabilities, I would scrape up the cash to get one. So long as I can get a reliable and measured output of light for a lesser amount, I personally see no need for me to pay more.
Remember, the dough is buying improved functionality.....not improved light.
