I would buy a Makita 13" tomorrow if I could find one. I beleive that it is the best saw for drop cutting tenons. I use the 10 1/4" saw for 90 % of the time, it would be nice to have a little deeper cut. I would also be interested in the Makita saws that are sold in the UK.
I find that the narow base is less affected by rough or irregular surfaces than a wide/ less flexable base. Tom
