Thanks, m_c, I'll face the rigours of JB's reading list in the morning! I'd seen the Homann site, it was very helpful and the ease of installation of the 540 is a bonus although sorting the electricals doesn't concern me as much as some of the other decisions! (It's just like wiring a plug, lots of plugs! )

I'll certainly keep an eye open for the sale! Thanks for your help!
