Have you considered Mr. Aqua? They have cube and long 7.5 rimless that look pretty slick... And if you top it with a Finnex Ray 2 you can grow pretty much anything. I know it's more expensive because it's not a kit, but I think it'll be more interesting in the long run, like more variety. But the Evolve 8 is a nice choice too.
How I feel about non-planted aquariums.
