Hi I'm an Art student in Puerto Rico; I know that has nothing to do with engineering, but I'm also in the same boat as you. I've also look into does colleges you mention and even thou I got an answer from Full Sail, I still can't pay that kind of money, specially when they raise tuitution every year.
So I've been looking around for different options and have ended up with some colleges that are still expensive but are a lot less expensive. UAD and 3dmx in Guadalajara, Mx.; Campus CTD in Ecuador; creaciodigital.upf.edu in Spain; and you can make a search in awn, in their school data base. Is really helpful.
About scholarships is kind of hard to get one in the states, and the ones that you can actually get are about 1,000 too 2,500 wish is nothing when tuitution is 53,000. But you can check out France, Germany, Finland and other European countries that offer free of charge master programs. Just got to go to their respective embassy to find out how it works and if you can apply. There was a website that when something like highereducationguide.info or .org; I can't seem to find it but maybe you'll have better luck, there it was explained.
Also there is a school in Argentina called Image Campus, is not a degree but it is specialize. I'm sorry if this ain't very helpful since I really don't know of any online degree that's less expensive and actually worth your money.
Even thou they don't offer much here is a link to 2 scholarships http://www.interactive.org/foundation/scholarships.asp
I hope I was some kind of help, good luck!^^
