I've seen that set at the markets here in Beijing. It's not a bad set but the school bus is eight bricks wide, too large.
I kinda like that Sluban brand, I've got one of their battleships and some (smaller) buses and a big old-fashioned fortress set I've not yet put together. I'd have to say it's the best Chinese brand, the bricks are the same size as Lego (unlike BanBao) and the clutch power and quality is mostly there. I haven't had any missing pieces yet either. The minifigs aren't that great but the price is right. Lego is really expensive here (double US prices).
Enlighten isn't so great IMO but those knock off Lego train cars that they make are passable. The tires of the cute little forklift that came with the boxcar smell highly noxious. That Enlighten tank that's pictured above looks like it's copied from another Chinese company (Sluban I think) so that's kinda funny, they copy from each other which I guess is what Lego did too back when they were starting out.
