I recently got a Parallax Digital I/O Board. It comes in kit form. So you have to solder all of the parts into place, but it is all through-hole. Here's most of the parts before I started. I have 8 relays not shown in this picture.
And here's the finished product. Sorry, no pictures of it during assembly.
Top view. I think this is a really cool looking board.
Bottom view. You can see that I am not an expert at soldering, but I got the job done. I've done some basic testing and it all appears to be working fine.
