[DUG] Installers

[John Bird]

Up to now I have been using the Inno Setup 4 installer, its pretty simple
and powerful.  (And written in Delphi)
The only thing it doesn't do that I would like is to be able to archive/zip
up older programs before I install an update (which gives a fall back if
there is a problem with an updated program).  Ie it doesn't offer actions
that can be done before the programs are installed other than creating
directories..

I noticed that the latest Firefox V2 beta 2 (which looks like a really
terrific version btw) now uses the Nullsoft Scriptable Install System which
looks really good too...

What do others use?
Being a single developer I don't really want to pay for high end ones if
free ones do what I want...
