I know they come at a not insignificant cost (Though they do show up secondhand regularly) but I am very sold on the Polemaster or any similar camera based alignment routine, followed if you want to dial it in very finely, a check with the PHD2 drift align routine. Just about everyone I know (Me included) who drift aligns with PHD2 has had one of those nights when you just seem to chase yourself around in circles endlessly, and before you know it, the night is done, the chosen target has gone out of sight or the clouds roll in! (I have most certainly been there)
Camera based polar alignment is literally a godsend. I don't think I would ever go back to drift alignment except in the case of commissioning a permanently installed mount when you know it is worth the time investment to get it really spot on and you should not be pushing to get data first night out.
