Another vote for Bullseye. I've found it to be the most accurate for me, and the most economical. I don't mind the low charge weights since I visually inspect every case before seating bullets. Doing it that way I've never had a double charge, or an empty case. I enjoy reloading, so I have no problem taking my time and being careful.
On the other hand, either of the other powders you mentioned would potentially serve you just as well as bullseye. All 3 are good powders for .45 ACP. Try each of them and find out which YOU prefer.
