That's a great price for a Condor, a pump and a scope,,,,, provided of course that it's in good shape and the seller is reputable. Keep in mind though that Air Force pumps are known for going bad and as far as I know it's real hard to find rebuild kits.
As for is it a pain in the butt to pump up a Condor... well,,, yes it is...... at least the first time filling the tank from empty. AFter that using the pump to just "top off" isn't bad at all.
On my Condor I top off the tank after I take 20 or 30 shots and it's really not that bad. Although my scuba tank is much easier :)
As for accuracy,,, yes,, the Air force rifles are very accurate and extremely powerful. My condor will shoot ragged hole groups with no problems at considerable distances....
