1500 head gasket set

I've had a bad experience with an Athena head gasket set - newly fitted last summer, it can't have done more than a few hundred miles.

But it's now blown. I'm not keen on trying another, but there's no other choice from Eurosport. Anyone got a spare head gasket set (not this brand) or know of an alternative brand supplier?

There's no evidence of any other faults and the head was skimmed before the new gasket was fitted a few months ago.
