I just open two finder windows. One open to a directory on my HD, the other to the card in a card reader. Select all the photos I want to transfer (usually all) and drag it to the HD. I have a folder for each camera. In each camera folder there's a folder for each year, then if need be, a folder for each month, or maybe for a specific event (e.g. 'france_july'). Very low-tech, I know, but it survived moving from mac to windows and back again over almost a decade.
