Paul, I think @ 6MP, image quality @ a printed 11"X17" size is somewhat 
dependant on the image itself. The data @ that file size has to be interpolated 
to allow enough data to print @ 11"X17". 
I've read that for a full 13"X19" print, @ 300dpi printer resolution, without 
interpolation, a 12 to 14 MP camera output file is needed.

That may be true in theory. I don't find it to be true in practice. In my 
experience, an 11 x 17 print from a carefully processed an interpolated *ist D 
file looks every bit as good to the naked eye as a 35mm print. YRMV.
