I'll see how I get on. £40 is still quite pricey at the moment and the alpkit one is good for hiking too.
I also have a similar headlight (gets dark up here. Have a heavy halogen one too). The lack of focus wont bother you if you're not doing anything too tricky (ice running, forest runs etc.). The few extra grams of the head unit are accounted for by the extra strap.
The important thing is that the head unit is stable. A wobbly light will piss you off quickly.
The battery units feel lighter than you'd expect, and usualy last ages.
