Terragen creates heightmaps, but if all you want is a heightmap to edit then just write a perlin noise function to give to a starting point and thus save yourself money.
Which is exactly what I said at the top of the post.
A noise pattern would be a grey scale texture that you repeat over the terrain to give it detail rather than just having one big texture streched over the whole thing.
You can see an example of this in this, the terrain is coloured using a single procedual texture and then the noise pattern gives it detail.
