Agreeing with Grover. I've also had leakage issues with some, eight others have never leaked. Just grab a little epoxy and seal the ends. Problem solved and great sounding caps.
Grover had another cap recommendation that has worked well for me: Cornell Dubilier Knowles 942C series. Look for the highest voltage available.

Depending on the circuit, you may be just fine with a 0.22 (LF Rolloff?)or 0.47 (stability?) Or, you could parallel a 0.1uF & 0.22uF.

Well, if you're going to try the Cornell-Dubiliers you can go up to 1uF. The only reason I recommended the smaller Miflex is because the 1uF's are just so enormous. They won't fit on the board but you could off-board them to a terminal strip. But they're also pretty expensive.
