Dixondalefarms.com has bermuda onion sets. Order some last night myself I like to use them for green onion they are so good in the summer pull one slap it between a piece of white bread and yum yum...

Are they still mild?I haven't had any sence I was a child.

If you intend to grow them mild be sure that the soil sulfur level is low. Sulfur causes strong onions. Also, like other onions give plenty of water and frequent feedings of nitrogen.
