if you buy them new not...pretty expensive...
but e-bay can be your friend...
lots of old school photographer selling them out. the cool thing is that they are pretty big (like 10x10 or 8x8cm) and the quality is amazing...and they have filters for anything..from basic color/light correction to what they call "creative" (read wird) effects...
I have a polarizer and a couple of gradient filters that I use quite a lot...
