Basically your choices are:
1) Buy a scalped one and pay way too much money
2) Pay for a bot to buy one for you
3) Wait a year or two for silicon shortages and demand to drop enough that it's reasonably easy to buy one.
You could try in-stock sites like NowInStock, but honestly unless you happen to be around actively monitoring those sites the very exact second they get updated you're simply going to miss out on one cuz demand and bots are that crazy.
