Hey All,
Well I did it...
Purchased 2 darkbusters last night from scuba.com they come with all the standard accessories plus a hard case thrown in with each.

For anyone else thats looking for a good price.
Once converted to Aus dollars was $1027 inc postage. Which was better than the aus sites that had them for 500 each with out cases.
Just have to wait the probably 3 weeks for delivery.... Waiting sucks... No cases from Aus arrival 4 days, Cases from US arrival 3 weeks.. they had better be good cases. lol
Def doing the yogurt filter. What do you thing works better strawberry or tropical yogurt. I prefer strawberry but don't mind the tropical.... I think I'll have to try both maybe more than once... 
Did you find the tub plastic breaks down. do you have to replace them often due to heat from the lights?
Sent a message to the guys at scubapix .com regarding the adapter and clamp for the mounting and they replyed with a cost of $198 per handle.
Is this roughly the price I should be expecting?
Peter.
