I got a spreader at TSC that was $349. It is all metal and I have only used seed in it so far. Worked just fine.
Strangely, the gearbox takes grease out of a grease gun and it doesn't say how much to put in there. The manual showed that it had gear oil. I pumped and pumped and finally figured it had enough.
