The fab lab university shop I just retired from teaching in bought one. The last time I saw it it had become the landing place for clamps and ear protection and such next to two conventional router table. In all the years I taught there teaching furniture design there was never a time when I thought having one would come in handy. Perhaps in a professional shop that made moulding profiles on long boards using a vertical moulding bits. Might be easier and safer than using a large diameter moulding bit
