Just wanted to post an FYI. Bought my dad a new rip fence for his aging but still in good working order table saw. The old fence was nearily useless. Did some research and decided on the MuleCab Accusquare. http://www.mulecab.com/products.asp?mnu_Products=1 Cost ranges from $190-$230USD for rail lengths ranging from 40"-72". Haven't used it to build anything yet. But from the install process and a few test cuts I can testify to its quality of construction and the accuracy it displayed on the few test cuts we made. If you're in the market for a new rip fence, or just aren't happy with your current one I'd recommend looking at the Accusquare.
