It's a tough decision, and I was there once. I was only getting 20 minutes dives in before I was very uncomfortable cold. Over the following 3 years I spent a total of approximately ~$1000 on 3 drysuits. Learned quite a bit. I eventually bought a Neosport farmer john 7mm wetsuit, which also keeps me decently warm, though I use it infrequently to keep it "puffed up".If you're on the budget, buy dual use undergarments that you can use elsewhere. Pretty much anything that is tight athleisure will work in Cali. You're not diving 30F waters.
$800 is $300-350 more than a solid 7mm wetsuit that will last and keep you warm, not an Amazon Belize vacation special. If it were me, I'd save up.
