I don't mean leaking physically - I mean electrically "leaky" which is really that they become more resistive and less capacitive. You'll find them less able to hold a charge after they've been sitting for a long time. After a while, they're pretty much just an open circuit.
There are plenty of poly caps out there that are very reasonably priced, by the way. Solens and Erse make good caps that don't cost a lot. Jantzen has some that aren't too expensive too. Of course, there are lots of boutique caps out there as well, the Mundorfs, Auricaps, etc. Some are kind of in between cost-wise, like Kimber Kaps.
