I've got a Romisen RC-N3

Be warned that when you register, use Internet Explorer, rather than Firefox. I tried to register with them, the page basically locked, and wouldn't let me fully register, while remembering my email address, and wouldn't let me register again. I don't think they ever got back to me, even when I finally found some contact info. Some sites are still twitchy about using anything other than IE. In the end, I had to create another email address to register an entirely new account, and I used IE. It went through fine.
Since I'm off with the family to Yorkshire next week (in one of those forest cabins - the nearest my wife will go to actual 'bushcraft'), I needed an LED torch (the DX order isn't going to make it, and my Maglites have gone walkies). Aldi have a 3X AAA 6 LED (and Xenon) torch for £10 at the moment

Bargain of the week is the 9 LED 3xAAA torch I picked up today. Very bright, 'good' plastic lens, rear clicky switch, seemingly aluminium construction. In
Poundland.
Its about 9cm long, 3 cm diameter, and comings in aluminium or metallic blue, and is under their 'ToolBox' brand. No O ring to seal the battery compartment, but there's a grove for one, and its easily done. I can't find it on their website, but this
http://www.alibaba.com/product-gs/249537137/9_LEDs_FLASHLIGHT_LED_TORCH_FLASHLIGHT.html is a dead ringer for it.
I hate Poundland, but if they have deals like that, I might go in a bit more!
