To be honest given the wealth of resources available for free I can't
see why you would need to pay anything to learn RoR.

If the free stuff doesn't click get a book or two. If, after that, you
still don't get it then I suspect that paying for a bunch of videos is
probably throwing money away.

What programming skills / experience do you have?

Html / css and Ruby language and little bit of PHP

Schneems - UT on Rails. => is this resources free
