Though not on that list the Funktion X01 is also a rebadged 226.

Yeah Rich, I heard an Opus club system http://www.opuspocus.co.uk/blog-news-events/truth-about-pa-sound-system-k.htm that was the biggest hifi I've ever heard, equaled only by a Funktion1 dance...

Mac, you may be able to pick up a s/h Tannoy TDX2 oop there-which is a rebadged XTA 226(minus the card slot).
I use one on xover/peq duties, it sounds great, transparent and flexible-it certainly...

The dbx will do what it says on the tin but it wont do it as well or as sonically satisfying as the equiv XTA. That said the base level XTA will run you a cool £2500 but wont sound 8x better.
