La Sportiva and Scarpa have always stood me in good stead although it is hard to get their less technical models in the UK. The new Brasher range are also well made and very functional (from talking to testers) although they don't fit my feet so can't comment beyond that. Zamberlan, Asolo and Meindl also make good boots. I've managed to trash so many pairs of Salomons, Merrels and Hi-Tecs that I wouldn't have worn them if I didn't get them so cheap or free.
And as far as I am concerned, if I'm going to be using boots in wet conditions (i.e. UK), I actually prefer leather over a water proof membrane lined boot as often the liner gets perforated with wear (or thorns, barbed wire, etc) redering the boot less than perfect whereas leather, if looked after, works very well and my feet don't get as sweaty in hot weather. May make me seem like a bit of luddite but merino base layers work better than boil in the bag hellys too!
