If you get on the game just in the hope of making millions $$$ fast and easy you will be disappointed.
Your best bet is to develop or at least park your names to cover the registration fee.
I register almost every day but seldom sell. Many of my names are not for sale (I use them for web projects) and those that I won't sell then I'll develop. I just don't have the time to develop them all.
Good names are running out fast (well most are gone, fortunately there are some drops) so if you need (or will need) domain names better register them today while they are still available. Also, value of domain names is bound to increase over time.
