If it was me,and new or used did not matter I would take that 630. and look for a used Unisaw with either a 1hp or 3hp.Take all that you have save and apply it to a new Biesmeyer fence and you will never have to upgade again.Should you ever(if you loose your mine)have to sell it,people will be all over it the first day.Buying a icon such as the Unisaw does not depreciate over yrs of use,while the choices you posted does.Crapsman????
