Hi and welcome to the Forum! Whereabouts in England do you live?
The supplied blade is a good one and can be sharpened. Mine's still going well, so I've not needed to sharpen it yet. You
can get higher quality blades, but be prepared to pay much more for a higher tooth-per-inch rating.
I'm a fan of the Triton router cutters and reckon there as good as CMTs - loads of carbide and very well finished. However, in the UK,
Wealden Cutters (Kent) are really excellent value, with a great mail order service too.
You've got some good kit there. I'd add the Workcentre Height Winder Kit for ease of use, otherwise your in good shape. Check in your Personal Message box.
Ray.
