These days the silent compressors are everywhere, go that route.
I have a older Porter Cable 2gal, semi reliable, but way to LOUD.
CAT are some of the nicer units, Kobalt also has a silent series, and HF just came out with one. All <$300.
ps you dont need much compressor to run trim guns...
If you want a really nice larger compressor, the Makita MAC series are also excellent, but heavy.
