Received a mailing list email this morning from YOSHOP and part of it http://imgur.com/a/uznbe included a deal for the NiteCore 45LM that grabbed my attention.
Black, Transparent and Blue are part of this deal apparently -

Cheapest these have been as far as I know. I posted a deal back in June through Everbuying for $4.05USD https://www.ozbargain.com.au/node/254638 but this is cheaper.
