Had a chance to pick up a Delta Uni Fence 50" for 75.00. Couldn't pass it up and thought, OK, if I ever need it I will have it. Well, I have used it up to 48" a whole bunch more than I ever thought. If you have the room, Jump on it.

Decide after figuring out what you will cut.

I rarely use my 36" fence but now I am making a kitchen and use it all the time. I think if cabinetry is in your future then get the biggest fence youcan.

I don't know about you folks but personally I haven't come across any sheets of ply in which the factory edge wasn't straight.
Of course us Canucks are generally considered to be more "straight" than you Yanks most of the time. At least back in the 60s and 70s...
