Thinking about upgrading from the Dyn 1.3SE

Where should I go from here? I have the 1.3SE and the 2.1 center in Birdseye... I was thinking about trading them both in and throwing in $700 or so on something else used. What do you guys think about the Special 25? Anyting else you recommend in the $3000 or so range used.
