My current breaker gets hot and doesn't trip when it blows, power goes out and switch is still on -.- , I'm worried about this breaker causing problems so I'm going to replace it. What should I be looking for? I don't want to just go to ace and pick up a cheapie, I want one that is going to do good by my rigs.

Looking for recommendations.
No offense, but if you have to ask these types of questions, you really need to get an electrician. It is obvious to me you don't know what you're talking about.
I mean come on.... your question about if you needed GCFI breakers was so lol. You are going to hurt yourself or someone else.
