Thanks Mechans - I can get the Chinook in 240v - I'm not sure however of how it compares to the 20/20.
Bpoletti - The Herron seems like it might not be quite warm enough in my system but appreciate the suggestion
Pbnaudio - The liberty looks good but am unsure about its Class A operation and heat generation - I am already challenged with heat dissipation in the current set-up. I am installing fans to alleviate this but want to avoid a lot more heat. Having said that - that is one disadvantage (I would have thought) of the Manley vs the 20/20 - i reckon the latter would run a fair bit cooler?
