I looked at Saga, but they wanted to know my name, address, phone number, email, etc, etc before letting me do anything by way of getting a quote. I refuse to use websites that do this. I know that often enough companies that do this are fishing for information they can then sell on to marketeers. Admiral car insurance used to do this, for example.
Try 'goodtogoinsurance.com'. I have a number of old medical conditions that I declare, and they have the lowest cost for long haul I've been able to find this year.
