Notorious T.O.D. said:
The microfence is top shelf stuff like Festool, Bridge City Tool, Leigh, LN Planes. It is more accurate, down to .001", than the Festool guide. It can be used with the guide rails or with the included edge guide. The safe and practical route may be to go first with the less expensive Festool guide and use the 30 days to see if that does what you need. If not then perhaps go for the microfence solution. The microfence can be used with virtually any router also, even with the Festool Guide Rails which may be an advantage also. Even though the microfence costs over double the Festool part i doubt you would be disappointed with the Microfence. I love mine.
