Thanks mate. Didn't realise they were that cheap.
Apparently I need to check into the legality of their use in Qld.
Edit - looks like up to 1mW are fine, over that need to be a member of Astro Society (IIS count?
) or occupational reasons.
Edit 2 - just ordered one off Trevor's ebay link. As I said, didn't realise they were that cheap. Should be fine for a night's use.
