I am not aware of a formal trade up program but my long term dealer was able to give me a good trade in on my old UEFs.
I've personally not actually directly compared the UEFs with the AQ 7000 but did find that the upgrade from 10UEF to 12 UEF (the glass top model at least) was transformative bringing an entirely new and improved presentation to the complete system. I have found it beneficial to damp/cover the top plates, the flickering blue LED is very objectionable.
The Denali also looks like a good option and in particular I like the look of the supports for heavy AC plugs it has -- the SR products still suffer from a lack of support and I need to resort to shims to hold in my very heavy original Galileo LE plugs - oh well
