Dark Summer is definitely the best out there! Only been going for a year, run by enthusiasts, free as well. www.darksummer.co.uk then follow the link to subscribe. Enjoy. Check out their forum as well mate.
Fall-line Skiing isnt half bad... Nice articles about small and larger resorts, kit and techie stuff and (despite clearly being quite proud of the British scene) only a few pages dedicated soley to Brits. Once a month at a couple of quid is better than not at all if youre a skeek.
You should check out Base Camp magazine... think you can send off for one throught their website. It is a fairly new magazine with some pretty cool articles. I think their latest edition will be coming out in a few months time, but their last one is worth a look.
