and from what I've read on this list, you seemed to have more dollars 
to spend on it than cents 8*). 

Hey, I resemble that comment :-)

I thought your numbers would be on the
high end of the spectrum.

Also true.  For the low cost end, I guess we could ask someone else.  Where is Finn anyway :-) 

With the Lycoming your total comes to 25,900 up to the prop.  Does your
estimated figure for the rotary include the prop?

Yes.  I included the prop in every figure I gave.  If you want to exclude the entire prop from the above figure, make it $24,600, because the FWF kit is only $3k for the fixed pitch version.  No reason to count the prop governor if you don't count the prop. 

  I'd like to exclude
that, because it varies so wildly and doesn't differ in fuction between
the engine types.

I included it in my RV-8 numbers because I insist on having a CS prop for this plane.  This probably does sway the balance toward the Lycoming a bit, since the primary CS prop for a rotary is the $10k MT electric prop.  Prop and governor for the Lyclone is "only" about $7k. 

BTW, I'm not sure I'm going to let Bob get away with saying that- "It isn't uncommon for the Lycomings to need a top after a few hundred hours.".  If the engine is broken in properly, and wasn't a run out pile of junk to begin with (insert favorite Lycoming joke here <g>), this will not be the case. 

Cheers,
