Hello Thai visa advise group

I want to ask for your help about my visa problem. I'm a Hungarian citizen and came here with a 60 days tourist visa. I did before an airport re entry stamp before and now I extended my stay with 30 days so I have to leave Thailand in February 17 th. I want to ask you, If I leave the country by airplane, can I get a 60 days re entry again? If not what kind of methods you recommend me? If I do a bus visa run how many days I can get? Or if I choose to go to Cambodia how many days it's takes to get a new visa?
