to use a shaper you have to have the need to run make many peices. Until you have the clientel it don't warrant the expence of a shaper. The router is more versatile and will do more in in the long run than the shaper. The shaper is like a router on steroids.
If you can warrant it running all day with the same set up it wil pay for itself.
I have been in the business and have retired, and sold my shaper but I still have the router and tble to take care of my old customers. Hope it helps, Woodnut65
