Thanks all, I must admit I hadn't considered dust extraction as most of this will be used for external cladding, so I'm planning to do the cuts on some saw horses in the garden, and the boards that will be used as flooring are for the ground floor which is going to be a big dusty building site because we're demolishing the back of the house and extending.
It might actually be more of a concern for other uses as that's more likely to be inside.

What makes you say that @bq ?
In terms of blades I've had Freud ones recommended by @dbr and I trust him on that, I'll just try not to make any slips.
