Glad you signed up bela hubbard. Welcome to the forum. Are you planning on running a lumber yard type of operation or are you just planning on making T&G paneling for your self. If you plan on running a business of T&G paneling, my opinion is to buy a shaper. They are more for production use. BUT, there are quite a few routers out there that can handle the job also. It really depends on what you plan to do. If you are like the rest of us, you will end up buying a router anyway. At least one. After all they are the most versatile tool in the shop.
