Hi jfacteau
I have made many out of MDF and they work great, the best fence I have used/made is the swing and pin type with a T & G inserts.
The MDF stock mills well and it's clean and true.
And it's cheap unlike the Aulm.fence type,with just a little work and about $10.oo of stock you can have a great fence and the fence is 50% of the router table.
