Regardless of which compressor you get, unless you are absolutely sure it has first class moisture removal I would add an extra filter filled with color changing desicant beads. If you do a gun or tank fill and all the desicant changed color, you may have moisture in the gun/tank and should consider emptying it and refilling with better filtration. That has never happened to me and I do not use a really big extra filter on my Yong Heng. What I normally find is on a little of the dessicant changed color and I can use it again on the next fill. Seems like it needs replaced after about 6 tank fills. But I vent the compressor every 5 minutes and slope the lines to the filters back towards the compressor and I think that helps. This is not expensive, especially compared to the issues moisture in the air could cause.
The other thing I recommend spending a little extra on is oil for a Yong Heng. I use Nuvair oil but there are several good brands. My YH is a couple years old and working great.
It's a little controversial but one thing I think you can save money on is a tank. I bought an expired Scott firemans tank ebay for about $100 and it works great and has for about the same time frame as I've owned my YH. I did not have satisfactory results from a cheap fill set, however. But a good fill set with an expired tank should cost around $300. It's a good "next step" after yu get a YH. But it can be argued you don't need to take the next step with a CS2. Just depends on how you want to do things and how patient you are for relatively slow gun fills.
