Thanks Malveaux but like Flumphy said Thomman isn't suitable.
Hmm.. I'm seriously considering buying €25 worth of stuff from damn Thomman just to get the pads! Maybe I'll buy a set of standard K240 pads as well as the velour ones, that comes to 25. But with shipping its £30 - the same as I paid for my Sr850's in the first place!!
I'll keep searching. And bumping.
