Compressor...air cooled or water cooled?

I'm waiting for my first PCP rifle to arrive, and am figuring out what type of compressor is best for me.
Will be filling direct to the gun (200cc cylinder on it).
My first thought was a GX CS4...but sadly too dear as anything over $NZ1000 imported the NZ Govt and Customs add on another 15%GST tax, plus Custom's fees, plus more tax on top of all that.
OK...the next best is the GX CS3 (or the CS2?), or maybe the Yong Heng.
The CS3 would do the job, but I'm told the CS2 is the same pump but 'naked' (no fancy outer case).
The Yong Heng? Will it last longer than the CS2/CS3 as it may run cooler?
I'll only be topping up the rifle cylinder once a week and the air cooled jobs look more 'simple' for my use, but don't want to buy one and have it die in a year because it's not as good as a water cooled job.
Either choice will still cost over $NZ700 shipped (but at least it stays under the $1000 trigger point for tax, tax, and more tax).
Thanks.
Grey, also no longer young and healthy

Grey, I am well past using a hand pump I have been using an Omega Trail Charger. I find it to be the best of both worlds with water cooling and an a fan. I have had it x 3 years and no issues with over heating Price may be an issue, it is what I clearly see as mid range model.
 
Here's mine. A little pricier, since it's 3 years after yours, but no bottles, bucket, stool, and nothing to break down after each fill, whether it be a 7-8 minute gun fill or a 3-hour 97cu ft fill. $658 for pump and 1 filter (hoses excluded, as they seem to be in your post). Takes about 8-9 minutes from 150 to 250 bar, and is VERY quiet. Hasn't gone over 41° C/105° F yet. Might do so when summer is in full swing. (This setup is outside, not inside).

Is the CS4 better than the CS3 & CS2?
 
I neglected to return to tell you of an outcome.
I bought the GX CS4i. Yes it was dear as NZ Customs wanted their 15% tax on top of the price.
But....it's great! The rifle didn't arrive until June/July. I fitted the Josef1000 quick fill (nice piece of kit), and have filled the 9015 cylinder about 6 times now.
Only use it once or twice a week at my indoor BR club.
So far the CS4i is performing well, and does a quick job of filling that wee 220cc cylinder on the Anschutz.
