I'd held off buying one up to now because I was perfectly happy using my
flip (nod) down mask. I'd tried one out, and was impressed, but didn't
fancy shelling out £150 for one.

I spotted some on ebay from a US based seller which looked pretty good,
and were going for ~£40. I bought one, it arrived today (5 working
days!!) and I'm really really happy with it. I paid £49 including
shipping. It looks very similar to the Screwfix offering.

I thought I'd share that.
