A full size stationary saw with a belt drive induction motor has the vast majority of advantages over a portable. If you don't "need" the portability aspect, I'd go with a full size saw....no contest. Accuracy aside, the extra landing space in front of the blade is much more generous on a stationary saw than a portable, making it safer and easier to get good results with. The induction motor is much quieter and has more torque. The extra mass makes it much less likely to move during a cut. It's a lot easier to make upgrades to a standard full size saw too...you can add solid cast wings, better fence, aftermarket miter gauge, etc. A full size cast iron and steel saw is more robust than a portable, and more feasible to fix in the event of a failure. They also tend to be nicer to use....you're far more likely to outgrow a portable. Is the difference in floor space they take up really worth the other benefits you give up?
The Delta 36-725 is another viable alternative to the R4512.
