Thank goodness I am no longer out on the fastrack, but will say that if your doing hobbiest type work I personally dont see the need for anything other than what you use now. If production is your criteria youll probably want a drill tub and frame table. There was a time when I was so overwhelmed with business that I incorporated a ritter tub and table and still barely kept up but when I closed the big shop that was the first to go. I ve seen quite a lot of this type equipment on the market for pennies on the dollar. I never heard of castle till about three yrs. ago but if I was looking I might zero in on it. If you are in a production setting it may pay you to buy a setup. Plan on dedicating approx. 300 sq. to the new addition. Enjoy JB
