I would always recommend the
Petzl Myo XP. The rrp is around £70 but you can always find it much less with a bit of googling;
£42 at Go Outdoors
A lot more than the Gamma but once you've had Cree you never go back
!
85 lumens on full plus a 'burst' up to 150 lumens when you hold down the button for spotting things of in the distance ( a claimed 97m). Cree is the way forward for all torches and lights these days; loads more power compared with halogen, xenon or traditional LED and much less power consumption.
(I treated myself to a Fenix E05 keyring torch after I found a few quid in my paypal acount I had forgotten about. 27 lumens from a single AAA. Compare that to the woeful 2.3 lumens thrown out by the Maglite Solitaire. Or try a Led Lenser P7 offering 200 lumens form 4 x AA compared to the 122 lumens of a mahoosive 4D Maglite?

Two things to bare in mind with Cree torches/headlights
1. There is no focus on Cree head torches. The Myo XP has a flip down diffuser which softens the light for use around camp or when trying to talk to someone!
2. Halogen and Xenon bulbs will slowly fade as the battery reaches their limit. This means that you only have a short while of their full potential while the batteries are fresh. LED and Cree torches/headtorches will provide consistent output throughout a range of voltages but then suddenly stop, plunging you in darkness. Always have spare batteries when with you if you go Cree
