I am considering the purchase of an entry level scroll saw. I have narrowed down to two that I think fit my requirements, the Porter Cable 16" saw and the Rikon 16" saw. I don't have any knowledge of scroll saws and am asking for input. I know of blade types and tools required for changing them and I have heard something about vibration. Which would be best? I just want something around for general use, not fine fret worth, etc. :tool:
