I am currently using around 30. They vary from large to small, but you want to hit a varied audience for your mailings.
It does require signing up for multiple gmail accounts to keep up with the mailings coming to you. One thing that got me started with the majority of these safelists was the "challenge" program I joined. It takes you step by step on joining the safelists and guides you on making a good living with them.
The program is fantastic and I really like most of the safelists used in the program.
If you are a novice, check my sig and its no cost to join.
