I will say personally that I feel the best starter package is from SCA Aquariums. It's pretty well priced, high quality, and starts you off with a sump opposed to an AIO. AIO can be great, but they're very limiting as time goes on.
EDIT: Just saw what you ended up with, that's a very wise choice. you will be MUCH happier with that tank over a BioCube -- Not that there's anything wrong with a BioCube, but most people start feeling very limited with which fish they can keep, and what equipment they can use.
