Steve,
I'd actually put my money on the table saw with dado blades (cabinet/furniture maker for about 30 yrs). It's usually quicker and just as clean with good quality blades. Also, if you use a router table (a nice little backup to a shaper) make sure you have a relatively late model router with plenty of H.P - An underpowered, older model is much more likely to burn up even with moderate use.
