WTB: Used MTB shimano shifter/brakes, derailer, skewers......

I am in need of a right ST-EF29 shifter or a pair of Acera (or about the same level) Shimano trigger shifter/brakes triple and 7 speed. Also would be interested is someone has a similar level front derailer. Need a front skewer, would take a pair. Also looking for a headlight and fenders (front suspension with bolt hole, rear has bolt holes too) if someones got some in their closet. Used and cheap preferred. Could trade shifters- I have a set of revoshifts and some low-end brake levers in descent shape, just too lazy to re-string the cable if I don't have to.
