Very good price on that one, but CO2 is not as economical in the long run as air and the pressure fluctuates with temperature, which can affect accuracy. If you have more to spend, I think nothing beats a PCP; The one-time start-up cost of the air tank or pump is a big hit, but either one will service multiple guns and pay for itself over time, if you shoot fairly often. I own a Benjamin Marauder, (M-Rod), that is probably the best PCP value in the 500$ price range; they can be easily found in lightly used condition in the 350 to 400$ range. the biggest complaint being the gun is heavy. If a 22 is big enough for your needs, then the Benjamin Discovery (Disco), is hard to beat, for even less money than the Marauder, It is considerably lighter, but is a single-shot only model.(no clip or magazine feature). both of these guns are very popular, easy to work on, with replacement and hop-up parts easy/cheap to get.
