I shoot two RWS rifles (48 and 52) and a match pistol (M5) but the trigger on my buddies Beeman R 9 is better than any of mine.
And the trigger is most important to accuracy on PG's, so pick a good one.
Were I you I'd get a 17 cal (cheaper and more than enough power for what you want), barrel cocker (not one that pumps up). Get one that gets 950 fps or more, and with decent scope meant for a springer (at least 4 power) Get some good pellet gun scope mounts, the rcoil can shift the scope otherwise. Do not use a scope meant for deer rifle or 22. the paralex adjustment is wrong for a pellet gun and the forward recoil of a powerful springer will tear up the retical in no time.
Don't be concerned with accuracy until you've shot at least 500 rounds through it, perhaps more. It takes that long for the barrel to smooth out before accuracy is consistant. I've shot my 48 at least 10,000 times and the other one at least 5,000 and it was the case with both. Use diferent pellets until you find the one your gun likes. Buy good pellets, cheap ones are not uniform and won't be accurate. Cabelas used to carry a sampler pack of RWSR that had 5 or 6 differnt pellets to try.
Both of mine can hit a shotgun primer at 25 yards ('bout the size of a squirrel's eye) with the RWS match pellet. Do NOT put oil into the air chamber as some would tell you. It can tear out the seals and springs on a powerful springer when the oil diesels (ignites under pressure). Don't store them cocked (weakens the spring) or shoot them without a pellet (piston hits too hard damaging seals, etc.).
Determine where the springer is made. Some of those made in China are cheap and worth about as much as you pay.
Sprigers are laods of fun, economical and just the thing for pest and small game. I too am on the verge of retirement; just made a pellet trap that wil allow me to shoot all I want...in my shop! Good luck.
