I am looking into getting a larger capacity cross cutting machine with dado head capability in the near future. Does anyone know of a SCMS with the the cpability of using a stacked dado head? I have the 10" Bosch SCMS and it has work very well for my current needs. I know of all the safety issues of cutting on the push stroke vs pull on a radial arm. I have used a radial arm saw before. I would not be doing any ripping on the radial, just cross cutting and dadoes. What does everyone think about the two? which do you prefer and why? Also would you buy a used old Dewalt or buy a new Original Saw radial arm saw (12")?
