Based solely on my own reading, and personal experience with the designers, I'd second the First Sound Presence Deluxe II ($2500 used, and you won't have the urge to upgrade any time soon), and I'd second the Modwright SWL 9.0SE. Finally, based only on user comments and price, I'd look into the aforementioned Herron VTSP-1A.
Between these three, you have a sure winner.
