Eusebius,
I have been looking for a replacement for Aperture because I know the inevitable will happen and it will no longer be supported. I hope that Serif has there DAM out by then. I tried Light Room but I hated it.
Take a look at Pixave 2 http://www.littlehj.com its inexpensive and may just work for what you need. I have it downloaded but have not given it a real work out.
I did change my importing habits though and use a file system in my pictures folder that would look like this for mothers day.

So it is easy to use any program to find the originals and save jpegs back.
