I have had several of the cheap analog meters of of E-Bay, and one digital bargraph meter. My current sat meter is one of the original analog needle types, but if is a Triplett brand bought at Fry's Electronics in Phoenix.
BTW, I know that you are just aiming at 1 satellite, but for those who have Dish 3 satellite system, here's what I do. I usually have the elevation setting close due to a previous set-up within 500 miles of the last one. I use a compass to get the heading, then set the dish pointed (azimuth) about 40 degrees or more East of the desired compass number. I set the Dish box for the middle (119 degree) satellite. I then swing the dish West watching the meter. There will be 3 strong signal peaks corresponding to the 3 satellites. I set the dish aiming at the middle signal peak, adjusting the azimuth and elevation for maximum signal. This works for me, and correlates with the given dish pointing compass number.
