Is anyone using Mistrals intake manifold?

This whole manifold thing is making me F%#$@ CRAZY.
Honestly I'm haveing a hard time with this thing, does anyone have any clue as to where I can find a manifold that will bolt to my motor that doesn't cost  $1200. I swear!! if it's the last thing I do I'm going to find a way to produce a bolt up manifold.

How are we coming off of the oval primary port into a 2.5 or 2.0in tube?
there must be a way to machine a plate that I can interchange different radius tubes. I'll draw it in CAD of what I think might work. Think about the machining process if you have any ideas on how this might work.
