I have to agree with ChuckD.
I don't own a bandsaw but from what little I've used one and what I read on other forums, a band saw does not always cut in a perfect straight line at a given distance. The blade tends to wander off true much like a scroll saw does. They call it "drift" and you must set the fence according to what the blade drift is doing.
Most people just mark a line on the board (like a pattern for a scroll saw) and just follow by eye to get an idea of what drift you have and adjust the fence to that angle.
So, what I'm saying is that you do not want to lock a fence in a 90 degree angle to the table or blade in this case.
And to make matters worse, every time you change blades (which is not all that easy to do) you must re-adjust the fence to suit the drift in the new blade. That is why the magnetic fence is much easier to use.
Unlike a table saw, you can not just set the fence 3/8" from the blade and expect the board to be a constant 3/8" thick all the way down unless you have adjusted for the drift.
I would like to have a band saw if I had the room for it but, honestly don't know that I would use it for anything but re-sawing wider boards. And then you still have to run them through the planner to get the blade marks out and get a constant thickness down the full length and width.
