You can hand reg a few and if you're creative you might have some luck (a lot of luck). Most domainers tell you never to hand register but personally, I have been very fortunate on a number of hand reg domains. You could also pick up a few domains at auction for a hundred bucks...
But now I'll give you the best advice any new domainer could ever get....
Only try domaining if you do not need the money desperately, there is a huge learning curve and most newbies lose an awful lot of money before they ever make any. If you have patience and funds available then do a little dabbling, the same way as you would at the coin slots. If the money hurts you should not be playing the slots because chances of winning are slim.
So ask questions, have fun, just don't overspend because odds are I might have to buy a couple of your better domains when the fire sale comes. That, unfortunately, is fact and a lesson learned for a lot of new guys.
