I know this may vary some based on tools but based on your experience, what has enabled that for you? I find that the air tools have less vibration but with my 27 gallon, it really can run them for very long before I need to let it refill again. Thanks!
You want more CFM. Tank volume is only part of the equation. 20-25 CFM minimum if your continuous use on small air tools like a die grinder or sander. 30+ if you want your air compressor to last longer

So pretty much in that $3,000+ for continuous angle grinder use then? Anybody seen a better value?
for compressor and tools in general get what you pay for.
another thing to consider is cost to operate, for continues use a corded power grinder will cost less to run than a pneumatic, a lot if running continues.
Yea, that is a good point. However, I’m looking for ways to minimize the vibration. I have corded as well but when I have multiple days in a short amount of time with a lot of grinding, it has been pretty rough on my hands / joints even with trying to hold it loosely and anti-vibration gloves. I’m hoping it is just because I am new to it but I’ve read about long term side effects as well.
As Jason mentioned, tank size may be less important than maintained flow rate. The advantage of a larger tank is less cycling of the compressor, depending on your task. The main difference to me though has to do with noise. Compressor noise. Lots of it for a large piston compressor. With electric you have the tool noise. With air tools, you have both. Yeah, I know, always wear hearing protection, and all that good advice. But real world? The downside of electric grinders/sanders is I cook them over time, either needing to just do the brushes, or needing to replace drive gears. On vibration on electric angle grinders/sanders, you get what you pay for. I think there was some review on the forum of grinders that including a review of vibration. “Better”, i.e more expensive machines can run smoother. That all said, whenever I can, I prefer pneumatics.
