If you're into realism, you should check out the Kyosho Mini-Z line. They have a lot of realistic looking minis although at 1/28th scale they are a fair site smaller than the Losi minis that are 1/18th scale. That being said the Mini-Zs have a huge following and a lot of after market support...
The Fazer is a fine rig but to run a 1/10 scale indoors is gonna take a ton of space. If you find you dont have quite enough room in the hall for a 1/10 scale you could possibly look at the Losi Mini B or Losi Mini T 2.0. Just a thought. IDK how big said hall is. :)
