New to windsurfing and I have some questions....?

I have raced dingy sail boats my whole life and I wanna try something new. I am wondering what board and sail combo I should start with. I am 6'1 and weigh about 215 pounds and am very athletic and strong and I cant figure out what I would need. I live by lake tahoe in California and the wind there can be gusty at times as it is a mountain lake. So if someone could help with a board and sail size that would be great. Also any specific board brands or sails that would help as I am looking to buy used first. Thanks
