Lessee, you won't find the best routers on the market at Wal-mart. I have a DeWalt 2hp router, a big 3.5hp monster Freud that is in my router table, and a smaller 1.5hp DeWalt for the small stuff.
In a router, you need to have the ability to use either a 1/4 or 1/2 shank. Not all routers will accommodate both chucks. So do not go to Harbor Freight and buy any junk that you can plug in and think it will work. It just might one time, but spend the extra money and either go with Bosch, DeWalt, Porter Cable, and the big Freud. All quality machines.
...oh, THAT kind of router.
I thought this was going to be an interesting thread!
