The personal edition is completely free. If you are not skillful in programming Lua, there is very little that pro edition offers to you besides having a command for emulating mouse-clicks. On the other hand, built-in Lua is a great enhancement more than worth the price of the pro version. Lua alone is also free (you can download it here : http://www.lua.org) but it's a bit "uncommon". Try and see if you need/want to go Pro.
