I like the ATP,Mighty,and Napa brand filter kits. They use the old style 727 filter,with a nice heavy duty rubber gasket. I hate cork,in this day and age,cork gaskets are unacceptable to me,they leak,if not now,after it crushes,it will leak,or weep in time. I have reused my Napa gasket 3 times already,still is better than a new cork one. I need to get a double deep pan,just need to save more $$ first.
