Good question. I'll be curious to hear what others have to say.
I found some of the videos on MiniatureMentor helpful:
http://miniaturementor.com/painting_tutorials.html
Individual videos can be expensive but if you subscribe to the site you get as many as you want for a flat fee (plus much lower monthly charge until you cancel... which you can do as soon as you get all the videos you want). These videos are, in my opinion, geared more towards higher level display quality painting. That may be good or bad depending on what you are looking for.
You might want to take a look at a Kickstarter for one guys painting videos:

He did two examples for Rivet Wars, so you can get a general idea of his painting style and video approach.

Those two are free. I don't know how similar or not they will be to his project. You'll have to read more about his kickstarter to find out. There's about 4 days left before the kickstarter ends... so check it soon if you think you might be interested.
