I thank you all for your great opinions.
In my simplicity, I had forgotten one of the greatest benefits of Hauptwerk! That is the ability to choose an instrument appropriate to the music being played, rather than having to choose an instrument able to do everything. Since I have a good selection of baroque instruments thanks to my friend Augustine, and I have the Smecno from Sonus Paradisi which excels at renaissance, I believe I will concentrate on getting the Caen.
I know many of you think the Poblet is "the cats pajamas", but, to me, it is excellent for baroque, not romantic. Even the Rotterdam doesn't do it as well as the Caen. And, as pointed out, with Jakes extension it is even more so.
Again, thanks to everyone for their input!
