Big guy and want to buy a kayak?

[BrokeLoser]

Hello, I'm new to this forum stuff and kayak's.
I'm 6 foot 2 inches tall and weigh about 245.
I want to buy and use a kayak for mostly saltwater fishing here in SoCal. I can't really afford a brand new one and would like to be able to find one used and already rigged if possible. I'm also hoping to find one around 12 feet long and very stable.
What brand or model would you suggest that I look for for my needs?

Thanks in advance...I'm excited to started Kayaking!
