Some people have complained that this site is hard to navigate, and it is (I will redecorate when and if I have time). Since you have come most likely to download the contentitem/placehere – module for Joomla I make a sticky post to the respective download pages.

Joomla 1.0.x- mod_contentitem

http://diebesteallerzeiten.de/blog/joomla-content-item-module/

Joomla 1.5.x mod_placehere (a.k.a mod contentitem for Joomla 1.5)

http://diebesteallerzeiten.de/blog/module-15/

Both pages offer links to current versions (scroll down to the last download link) and previous versions (not recommenend).

You find some info on how to use the 1.5 module here.
