Or you can probably get an LED Lenser SEO 5 on-line for £40. 3 x AAA and 180 lumens.
My sister got me a Petzl tikka RXP (now reaktik??) and I was initially dubious about it being a usb recharge only light. But, it's actually been really good and I don't really miss buying expensive batteries.
What I will say is I think the Alpkit ones might actually be pre-existing Chinese units just branded up as Alpkit - I'm sure mine I'd seen on sale elsewhere under non-brand but clearly the same basic unit. Not difficult these days to make a good quality battery powered LED headtorch for not much money.I'm sure the USB rechargeables are great for local stuff or use from a car, but for anything in the mountains I don't think you can beat a torch where you can just stick a couple of spare AAAs in your bag.
Petzl Tikkina 13 quid in decathlon. I lost my Gucci petzl yo and was shocked at how much a similar one would be also the battery life on them is shit so looked at the tikka plus sort of ones and they are expensive and have worse battery life than the tikkina. Only has two settings but they are perfectly adequate for all/most settings
More controversially I also like Petzl's Reactive system. Not everyone does (you can override it to Constant), but when walking in being able to let your eyes adjust slightly by having a minimal amount of light while walking on a reasonable footpath I find useful. As soon as you want to look at something in the distance it automatically shines brighter to work out which bit of crag you're at.
I've an old Petzl Tikka+. It has manual reactive lighting, three brightness settings and a flashing mode and you cycle through them pressing the button successively.
