While I would love to have a worm drive saw, I haven't been able to find any made for the European market. I have the Bosch GKS 18V 57G cordless saw that uses 6.5-inch blades and has two 5Ah lithium batteries. So far, it plows through anything I cut without bogging down, such as 23mm MDF. It is the only cordless Bosch saw here that has the blade on the right side and works with the Bosch guide rails. I went with cordless because most of the places I go don't have commercial power. Fortunately, all of my Bosch cordless tools take the same family of 18V batteries, so I'm never stranded between charges.
