what to do?

I have posted here before and was fixing to get knee deep in the airforce guns and a few things happend and knocked me out for a little bit (layoffs suck) but I had some time the other day and pulled out the gamo (shadow sport) and I am just not happy with it. I can take and sight it in and with in 4-8 shots it is off again I have thought about the scope and just realy don’y want to put no more in to it….and here is where the question is I am wanting to just get one gun to squirrel and rabbit hunt with and I am depbating on the .22 condor with co2, and co2 for the reason I have 3 tanks allready for the paint guns. and co2 refills are really cheap I want to say for a 9 oz tank it will cost about 1-3 bucks to get them filled…How does the condor shoot on co2 and how does it performe.. I know tthe temp. effects it but i live in the southern part of bama..so it doesn’t get to be real freezing but a few days…the condor I am looking at is on pyramid air with co2 tank,scope .
