John,
Currently there are no 'retirement visa's' available for the US - although I seem to remember someone once a few years back trying to push a bill through to create one so in the meantime your options as Fatbrit mentioned are somewhat limited.
A B2 visa is long stay tourist visa; however you'll need to demonstrate ample proof that you have no intention of attempting to emigrate to the US.
The only other visa's that would be seemingly worthwhile would be work or study related so I'm not sure how well they'd fit in with your retirement plans.
A B2 technically would allow you to stay for up to a year at a time however there are tax consequences that will kick in after ~180 days with both HMR&C and the IRS.
