Snowboarding newbie

I started boarding last year and have always borrowed my friends dad’s gear. I’m getting more in to park riding, and want a board that is CHEAP, and good for general all around riding. Need some advice on cheap brands or websites to buy new, or some brands to keep my eyes out for on fb marketplace. Not very serious about devoting a ton of money, just want a good quality board that will do me well for all around riding. Also size? I’m 6’4 210 lbs. size 12 shoes, Was considering a 162-166, does that sound about right?
