I have a bench top model (delta) which has been a great tool. Probably one of hte best I have. Having said that, I'm going to replace it with something bigger. The main reason is the motor. I want something that will stand up to hardwoods better than the portable while being quieter at the same time. I'm glad I bought the bench top thought. I'll keep using it until I replace some other the other tools that I have that are really lacking. If the money isn't so important though, I'd get a floor standing 15" model with a closed base and a proper motor.
