Best SPIA Rates - I Need help (65 Male, 20 Yr Period, 100k)

I am looking for the best rate for this case. I looked online and through a BGA. It is for a 20 year payout (not lifetime). $100,000 deposit. Male age 65 in Ohio.
Current highest is $552.57/month from American Equity. I ran into a website online from an agent that quoted $564 but it turns out he is not a BGA so won't tell me who the carrier is. I suspect it's a smaller carrier.
Any ideas who it is or anyone that can beat $552.57?
