please don't flame : it's an editor-question

Hi I use PHPed for ages now, since it has one feature that i definitely need : if i have used the variable $fooBar somewhere in a script, then i just have to type '$fo' and the editor shows me all valiables that start with '$fo' and i just have to hit Enter to use it. I know of pleanty editors that have that feature for php-functions, but i want it for variablenames. PhpEd has lots of bugs, which are not fixed since it's gone commercial. I can't afford 299$ for an Texteditor,so : Does anyone know of a free/cheap Edtor that has this feature? thanks Sebastian
