If you can't justify you design decisions then perhaps you need to reevaluate your design. After all, it's a prototype.

Dave,

My technical design options were explained in detail in my project thread.
I don't expect anyone to agree with me, or even understand it.
And my prototype works just fine, thank you.

Positive technical contributions are welcome and can only increase our level of knowledge.
That's what John is doing here.

Concerning the Harald's board versus my project costs:

- I don't know how much a Harald's board cost.
But if it does cost above 15 Euro, is more expense than my solution (hobbyists like myself just spent money on parts not in stock, and the labor is "free");

- Even it is costs below 15 Euro, it doesn't fit my needs.
What seems to be superfluous to you, it is essential to me.
I want to be able to monitor my flash operations with "bells and whistles" as you put it.
And an additional 3.3V power supply is absolutely essential for me, as I do not want to depend on the calculator batteries during flash and I do not want to depend on the weak internal 3.3V supply in the USB-Serial adapters.
