You can make your own unloader with a piece of pipe just big enough to fit a .45 ACP round. Cut a step in the top of it that the bottom of the .45 case, up to the top of the groove, will fit in. The pipe should be cut down a bit less than half the way around. If you want to get fancy you can knurl the bottom part. I bought one of these for $3 about 15 years ago and have felt no need for a more expensive device. The cases will slide down the inside of the tube into a box, or you can hold your hand over the end until the tube fills and dump them then. Fast, simple and cheap!
I've had little trouble loading clips manually, so have no suggestions on a loading tool.
