What is the best visa option for staying in Thailand for 6 months and returning after 6 months?

Hello, I submitted a question regarding staying in Thailand for 6 months and what the best visa would be for it which appears to have been deleted. I'm trying this again. I would like to leave October 1 and return April 1. Is this possible with two tourist visas and 30 day extensions or is there a better way to achieve this? Also, if you choose to delete this question could you please let me know why it isn't an appropriate question? Thank you.
