Hi, For the same reasons, Charles recommendations are right on. I prefer Bosch (have 3 total) the 1617 here in the US. They make a kit EVSPK that comes with both a fixed and plunge base. The plunge base is what you'd use to cut our that circle. It has stops so you can cut the circle in several passes. You will need a circle cutting jig of some sort. Bosch makes an edge cutting attachment that will also work as a circle jig. You can use the fixed base and the Bosch in a home made table, which won't help with the circle cutting, but for most other uses, the table is the safest way to do routing jobs.
Not sure about Canadian machines, but I think Bosch uses MOF as their model designation. The issue of orphaned machines is a constant on this Forum, but never for the brands Charles mentioned, especially the Bosch machines. Collets are very precise devices, and work by squeezing down just a few thousandths on the shank of the bit. They are easily damaged and can't safely be used. Do get something with a half inch shank, the 1/4 inch shank really limits what you can safely use the router for.
I must say that I'm just about had it with battery operated tools. The batteries fail and then you discover they've changed the form factor, connectors and/or voltage and then you get to pay a premium for leftover batteries, try to have them rebuilt, or toss the machines. I really like my DeWalt 18 v tools, but the 20 v adapter is junk and the 18v batteries are now double the price they once were.
Finally, I just don't care for Ryobi products.
The more I do, the less I accomplish.
