I'm wrapping up the details of my next cabinet saw purchase but haven't decided yet whether to get the SawStop Industrial 3hp or 5hp. The 3hp cabinet saw I had previously served me well and never seemed to lack power. Rob Cosman in his review of the same saw stated he never had a situation where a larger motor was needed. As a DIY'er my needs are certainly much less than his. Are there circumstances when a larger motor is helpful? Thoughts?
