If you have a ecp account or know someone who has, get a new 1 from there for about 5.50. The rrp is 40 odd quid, but if you get the discount its a steal. Get two while your at it, you don't realise how stiff they go until you've felt new. I can vouch for the quality as well they're perfectly good. Not as good as the leccy windows I've got in her now though...
