Hello,
For those looking for a mapping tool without all the noise of tileed then you might be interested in AshEdit. It is pretty simple in concept, as in you place tiles yourself with no autofill or anything, but there are lots of tools and things included (it feels like a sprite editor, only the tiles are pixels.)
I've used it for at least a half dozen (probably more) games. I made it when I was developing the precusor to one of my games. The game was going to be called Ashes Fall and that's where the editor got its name. The game never got finished but it went on to become a different game and the map editor survived and has been worked on quite a bit since.
You can download it for Windows and Linux on IndieDB: Downloads - Wedge - Indie DB
