I have the Wixey in my shop and use it constantly when I can get out there. It is non-replacable when one is making angle cuts, or when resetting the blade to the table levels. It can be used on the drill press and the bandsaw as well. All of these items work extremely well in setting up saws and drill presses. Accuracy is deadly!
However, look at this one as I think it is a bit better simply because it features an 'auto off' option...

BTW, this Peachtree has some excellent offerings to the woodworking family. They are close to my home and I always drop in prior to going on over to the local Woodcraft or Rockler store. (I check prices to see if I am getting a good deal at the bigger stores.)
Peachtree always has a great selection of sandpapers in stock and in all our favorite grits. They keep their supplies up to date and I have yet to not find something in stock or being replenished within a day. They also do very, very well in stocking all the plastic adapters for dust collection systems. [
