I was just talking to Jake (psykokid) about this...I am sure he'll weigh in sooner or later. He had a nano in his 60 standard and it was kicking up a decent wave, but he upgraded to the full wavebox and I inherited the nano (and found it worthless on the 24" tank). It got traded off, otherwise I would let you try it. Maybe someone else will step up.
I would think about going for the big guns, especially for the cost of even the small one. You will be more satisfied with the wave, 2" vs. 3/4", and the gyre it creates makes for some nice, broad, healthy water motion.
