Thanks all for you me input, I have gone for the Diamar Vipec 12 in the end for the extra safety. I read the article link posted above and that swung it. Managed to get brand new Scott Cascade 95 skis and Vipec 12 bindings for £393 so I'm sure these will do me fine.
Thanks again for your help.
Final thing, I have used avalanche transceivers before but don't own one. I have used Mammut Barry vox and Pieps DSP and found them easy to use in all modes. On a bit of a budget, any one know of any good deals on them, or cheaper alternatives. Also would consider buying second hand.
