There's no point in buying an MX5 if you can afford a Ferrari.
I've never heard a prospective ferrari owner considering fuel economy as in the opening post where he alludes to the economical benefits of diesel.
I think you'd be ignored by a ferrari salesman if you did.
As a result, the posts drew from this that money was not unlimited and that costs needed to be factored in to a degree. Hence suggestions that the extra money required going from 6.5 to 8.5 should be considered against the actual need for the length and size of boat ie useage/serious weather capability etc
Polwart: I can see the benefit of a cuddy or shelter to some degree for wind protection and spray etc. Though i don't personally see the need for a bigger boat to provide console storage and loo though!
If money isn't an object, my favourite is Goldfish for the south coast and Protector for North coast.
