I have both. I have the grizzly 3Hp. I'll take the shaper any day. less vibration. many cutters have two shapes on them ie. 1/4" and 3/8" round over so there is no savings. I find that except for the smallest bits, the shaper does well with 1/2" router bits. And bidirectional is a great bonus when shaping woods that tearout easily. By the time one buys a good 3hp router, table, fence, and raiser close to $1000 bucks is invested. A 1 1/2 Grizz shaper with all that is only $425!
