Key selling points
Can I put a bigger CF bottle on.
How much does it cost
 
Before a brick and mortar or online store I'd ask myself a few questions. First, a realistic appraisal of what I expect the airgun to accomplish and, second, what's the budget. Caliber/ammo choice would follow. Personal preferences like; wood or synthetic stock, traditional or bullpup styling, length/weight should also be considered. Next, Google and YouTube searches to narrow a list of candidates. I'd consider aesthetics and ergonomics at this point. Searching forum archives for real-life owner experience, followed by direct questioning on forum, should help to finalize decision. With one, or two, in mind, I'd search best price, recognizing scrutiny of seller is part of the process. WM
