Another factor in favor of a compressor over renting nitrogen tanks is that after you factor the costs of the nitrogen tank rent and fill expenses you get nothing back when you finish. I think the residual value of a used Chinese compressor will be very little or nothing. However, if you purchase a Daystate, Nardi, Airetex, or Bauer, you can use it
for years and it will retain a large percentage of its original purchase price if you resell it. Let's equate this to air rifles. You can buy a Xisico springer for $150, use it for years and it will be worth little to nothing in resale. You can buy an FX, Daystate, Weihrauch, or other quality air rifle and get a large percentage of its original price back in
resale if you take care of it. Nitrogen is rent and fill expense, a compressor is buy and sell when you're done. The residual value of a good compressor is the factor many fail
to consider. My Bauer will serve me for years, and my resale market is not limited to air gunners because a Bauer is used for diving, paintball, and other applications as well. I even have owned the original Shoebox and a Shoebox Freedom 8 and was able to get back 90% of my investment after getting free fills for a year with each one.
