I'm a big fan of Grumo Media (http://grumomedia.com/) and Epipheo (http://www.epipheostudios.com/) short-form (60-120sec) ones.
From what I hear, epipheo is ~$20k for a 120sec video and grumo is $5k per 60sec (60sec min).

So, which videos do you like best (not necessarily only from these 2 studios)?
And, if you happen to know, What studio made them and what do they charge?
