Webmasters and developers don't need a whole lot of money to spend on tools in order to work efficiently and be productive. Here is a list of free tools that help me run my everyday webmaster chores.
Notepad++
Dreamweaver and such designing tools might have become very advanced in the recent years but I am still far from satisfied with them. I prefer to do the coding with a simple text editor and be in total control of the code and not end up with unnecessarily long code. Recently I discovered Notepad++ which has the few bells and whistles that are desired by hard core programmers such as code highlighting, Regular Expression Search/Replace support, capability to extend functionality with plugins and nice depository of contributed ones. Worth your attention.
