I've found a site with these for sale, they are TUV approved and cost £120. Very limited numbers, these were once available via Irmsher so i'm not sure if they are these or not, i'll be finding out on Monday.
Anyone else interested in these?? The company overcharge P+P so one of us could go get them and take them to 's.
I'll let on which company has them once i've got mine ordered as i'm not losing out :P
