There are also XeTeX and LuaTeX which allow the direct input of greek 
letters. Using a good font, you can just type (or copy-paste, if you 
don't have an appropriate keyboard) any letter you need. A minimal 
example for lualatex:


\setmainfont{Linux Libertine O}

αβγδεϵ Σσς


You might also want to have a look at the babelbeta package which allows 
latin-based transcription for greek (for pdfLaTeX)
