better than birdog?

Is there a portable meter more precise than the birdog?
with out going the expensive way of a spectrum analyzer? With the five LNB on Directv soon to be the only dish going to be put up it's difficult at times to ensure accuracy to the tune of five sats and to conclude that i'm riding the lobe instead of the sweet spot. even with dithering. The birdog is great and gets the job done but I'd like to cut down on those trips up and down the ladder...
