Just finally got a chance to install the coolest piece of equipment in my shop. It's a digital depth read-out on my planer. It wasn't made for the machine, so I had to drill and thread holes and figure out how to make it work, but with my bad back, not having to bend over and look at the pointer on a ruler will be nice. Not to mention the fact that this thing is deadly accurate down to 1/64th of an inch. If you don't have something like this, it's worth investing in.
