Without knowing what you're looking for in a network, why you think you may want one, or anything about your channel, that's a near impossible question to answer.
There are hundreds of threads already here talking about people's experiences with various networks that you could read or, if you're anxious to jump into it and test the waters, find a network without a lock in and see how things are for yourself.
Your channel is at a size where you're not making any money anyway- so it's not as though them taking 10-30% would even amount to anything.
