Hi Buck,
Difficult to give any precise suggestions about scopes as the pricing policies in the States are so much different from the UK. Also, over here, we seem to have quite a bit of "price snobbery", meaning that if you don't possess 4 or 5 high end scopes, you are somewhat lacking. (Sad crowd sometimes, the Brits!)
BSA have a good reputation, but it's worth bearing in mind that most scopes of modest cost nearly all come out of the same few Chinese factories and are simply branded and then priced accordingly. We have retailers selling "own name" scopes thet are identical to big names but at less than half the price. I'm not 100% certain, but I would guess that "Leapers" is a take off on "Leupold"! Your own countrymen (and gals) should be able to point you to reliable names at sensible prices over there.
The important things are, that the scope is manufactured especially for air guns, due to the hard double recoil and also make sure that it is parellaxed for 35yards. I understand that many scopes for powder burners are set for 50 and 100yards, which is no good for airgun hunting. The other point is that you really need very solid one piece scope mounts, preferably with a stop pin, again because of the recoil. Less than solid mounts will simply walk off the rear of the gun after a few shots!
These suggestions go for any full power air rifle, not just the CFX.
In my case I'm waiting for an AGS 3-9 X 40, which has been suggested by more experienced friends as a good scope at modest price ($68 in UK). I haven't got it yet, as it is to be a Christmas pressy from my daughters!
Happy shooting whichever rifle you get. It will probably be the start of a collection.
