Howdy,
what do you mean by one that "won`t rip you off". Basically there is two types of training facilities. The once that have a fairly good name and offer good training and than there are so called license mills. Of course, the good schools have their price.
As for schools offering training over the net. Not aware that anyone would (completely) do so, as yet. I know that AGS has a distance study course (that still requires a week on the site training). You might also want to try Embry Riddle, since they offer a qide variety of courses over the net (or distance study).
Cheers
