In reply to The Ghost Rider:
I've had MSR Lightning Ascents for something like 8 years. They are very strong and reliable, I've seen lots of cheap snow shoe binding break off the shoe, so although expensive I think the MSRs are worth it in that sense.
They also grip well on harder snow with an aggressive crampon and the serated metal strip frame (as opposed to the more common tube frame that slips on hard snow.
I'm not sure how much use you'd have for them in the UK though?
BTW, snowshoes are pretty crappy for walking around in deep powder in forests! They need to be huge to stop you sinking in a long way - you might as well just use forest skis. They are much more effective on harder snow or crusted snow I felt smug that day!
