Been thinking about this response for a while ..so FWIW: First, I hope Micah does not think I was refering to the TB when I referred to R&D, I think this has been researched quite well.
I was thinking of the cost any small company encounters when it puts any new product on the market, especially when the demographic is small/limited.
My concern is we rely on several people on this board, aren't we indebted to them in some small way? jj
