Do a search for "Morrow AH levels a matched set". There is a picture of my artificial horizon rig. Accuracy is very good and it is a relatively simple home build. The bubble won't work at night not will the old trick of a pan of any liquid other than mercury. Set up is easy, 360 degrees of sky available and even the dimmer navigational stars can be used.
