I got mine from Bunnings for $6, it's not in a terrarium but it's doing OK aside from some blackened leaves (apparently a sign of stress).
The only thing to add to gamblor is don't water it with tap water, pick some distilled water from Coles/Woolworths (roughly $2) when you grab some peat moss (about $5) 'cos they don't like chlorine etc.
This link has done alright for me so far re. info.
Anyways, today's victory is finding some new shoes, from $80 to $40. And realising I had a whole bunch of awesome stuff stored at my sister's place, which I've now reappropriated.
