"Are you going to buy the inline oiler?"
Eddie, not sure who that question is for but since I have the second largest "mansaver", I'll respond -
I'm NOT a fan of inline oilers, been using air tools of one kind or another since the early '70's and always just "add a few drops", haven't had a problem that could be directly blamed on this practice.
From '78 to 2012, I worked instrumentation in two different rare metals plants - both were union, so pipe fitters ran pipe, welders welded, etc... Doubt if I could count the number of times I got screwed into complete disassembly of pneumatic instruments that wanted DRY CLEAN air because of some dumb/lazy pipe fitter that hooked up an "instrument air" line off a line that already had an oiler upstream
As to home/farm use, unless you intend to DEDICATE a hose to the air driver and KEEP it and the oiler WITH the driver, odds are that you'll end up trying to paint something with an oily hose, or put an oil film on something you were TRYING to blow the dust off of so you could paint it.
That's my experience/advice, worth every penny ya paid fer it
