Yes they are very affordable, so affordable that the cost for the first two years is free. Its called the two year warranty and should be used when needed.
Otherwise your right, I looked and a new oiler is around $5.
One other thing I found when looking is a IPL for a Poulan Pro 4818A that apperars to be the exact same saw as the 5020 but for a 18" bar.
Anyone seen one of these out there?
You sure about the 4818? They make a PP4218, but I haven't heard of a 4818. The 4218 is a little different. It has the no-tool chain adjuster on it and an inboard clutch rather than the outboard clutch the 5020 sports.
