What PE ratio is good to buy?

Hmmm, I've been eyeing this stock for quite some time and it seems like a solid investment. But before I pull the trigger, I want to make sure I'm making the right decision. You know, the PE ratio is always a key indicator for me. So, could you tell me, what PE ratio is generally considered good to buy? I'm not looking for a specific number, just a general range or maybe some guidance on how to interpret it. After all, I want to ensure that my investment is not overvalued and has potential for growth. Thanks for your help!
