The ones I have seen are metalised paper and do have a deserved
reputation for being antisocial. They split open and emit clouds of
evil-smelling magic smoke.

IIRC, the 'X2' marking means they are designed to be connected across the
mains (from live to neutral). A 'Y' or 'Y2' (which is designed so it cannot fail
short-circuit) is used between one side of the mains and safety earth (ground).
The latter generally have a smaller capacitance than the former.
I suspect any known brand would be OK. I must admit I never buy components
on E-bay, I go to somewhere like RS components or Farnell. They may be more
expensive, but it is less of a gamble.
