The cs4, being portable, you can take it anywhere. If you are an airhog.. your option is to use both, a bottle and compressor at the same time. Shoot your guns and fill off the bottle, and refill the bottle as you shoot. My brother and I run a cs4-i nearly non stop between the two of us when using the big bore guns. The cs4 models can handle running for hours and with the auto stop, we set it and forget it. By the time we come back to refill, the tanks topped off and the water is usually cooled down too.
We used to use one of those big gold filters, total pain since you can't easily mount it. We have the new GX filter on it now. You will want a filter for sure if doing this as you'll be consuming a lot of air and you won't want to be going back and forth bleeding the air.
If you're not in a position to get all of that, the cs4 you can grow into. If you do not think you'll be going to a bottle and or using a ton of air the cs3 would be ideal.
If you want a total home set up 5k1 or 5k2 the YH is cheaper, but it's very loud and you'll be spending more and more money just to support it. I ran a YH for about 2 years.
