wouldn't be without one.

We have had two, the bunnings one lasted 6 months, worked great whilst it lasted.
The next one was more expensive and is dead accurate. we got it from a woodworking machinery co. in melbourne. Found them on the net.

both units were about the size of a (fat) match box.

If you get one without an absolute zero degree button and have to teach it to find zero degrees, it can be a pain if the batteries go down and it looses the taught angle.

There is quick fix if you are have to change a battery and want to level a mount without a re-calibration of zero.

1/ set it on a table, press the set zero button, and turn it round 180 degrees.
Real zero will be half the reading. - just add or subtract this number during your mount levelling.

I know this is obvious, but in the middle of the night it might not immediately come to mind, so I thought I'd mention it.
