Try justradios.com (in Canada).

They have both X and Y type capacitors, some application advice for  
them, good prices, and fast shipping.

I AM a happy customer of theirs.

Y2 Safety Caps @ 250VAC (film)
0.1uF 250VAC.....$2.69

X2 Safety Caps @ 275VAC (film)
0.1uF 275VAC.....$0.79

I suggest you carefully evaluate whether you need 0.1 uF as original.

NOTE: My suggested arrangement is to put one X cap across the line,  
line to neutral, and one Y cap from neutral to chassis.  Failure of  
these types of capacitors is extremely rare, but if it should happen,  
with this arrangement, and assuming a fuse is in the hot line, there  
is no danger.
