Dessicant driers for flawless paint. Best for the money

I bought the metal tube one from Harbor Freight (not sure if they still sell it). When the desiccant beads finally gave up HF didn't have them. I found some at Amazon, but never ordered any. I don't paint much and found a few things that help. I added a second compressor tank 40' or so from the main compressor. My theory is that the air would be cooler at this point in the line and more water would fall out of the compressed air. That seems to be the case plus it's 26 more gallons of air after the 60 gallon main tank. When I paint I still run through the empty desiccant tube as a little more water will fall out naturally. I also drain water from everything before I paint. It all seems to help.
