I have a Delta contractor saw and the original fence needs replacing. I have recently seen the reviews in WOOD magazine and the top rating for the Biesemeyer home fence. I have done some additional study and the cost of the commercial unit is not that much more. I have also had some strong recommendations for the Delta Unifence as the only way to go. I am a hobby woodworker but am interested in trying to get the best available for reasonable price to handle multiple tasks. I have seen a lot of articles on auxilary fences and jigs for the Biesemeyer and it seems to be the more popular. Expert comments???????????
