Just a follow up and a bump for Ingo's board. It was a breeze to install. I have a problem with my clock connector so I didn't actually install the board with the clock in the 12 o'clock position. No issues. I ordered mine with blue LED's which look great and Ingo even sent the white ones along with it. Nice. Super good quality build and red diagnostic LED's on the board. Nice nice. And a last little nicety, which I didn't know and Ingo just informed me of, when the machine is off, the clock keeps real time! Really? Don't know how that works and I haven't confirmed it yet because of my connector issue but if that's true, way cool.
Keep in mind Ingo is a lawyer and does this as a hobby, not a business, so imo he is helping us, not us helping him. Also, he is half way around our world so his timeframe is different as to when he responds back.
I don't know anything about the Rottendog board so I can't compare and if you need a board immediately then buy local but if you can wait a bit, go for Ingo's board. You will not be disappointed. And as an added bonus, it comes packed in german newspaper. Affengeil!
