Does anyone have any experience with the router inlay kits that use pc router collars and a bushing that goes over them so you can rout the inlay and the recess with the same template? I am have been curious if this is a good way to go. I know you can't do detailed inlays like this, but I wonder if this is a nice thing to have around or if I should just do like Wood Guy and practice routing them free hand? Just curious if people love them or hate them, or are completely indifferent
