replacement slave cylinder?

hey guys,
thought id tell ya about my trip to Mc calmans 4wd park on saturday, every thing was ok untill the clutch slave cylinder decided to bleep its self, had to drive from murwillumbah through surfers paradise and all the way home to loganholme with out a clutch!, wasnt too bad though the only hard part was getting moving once i was unlucky enough to get a red light or 3 then i had to jump out and push until i could get it to pop into 1st. not that hard, i actually started to get the hang of it, so i spose now i have to ask, can anyone give me a rough idea of how much i will be up for to get thee replacement slave cylinder?
