I have a Caiman X I paid about $1400 for new, three P35s, an original Avenger, and a Prod (my first and I still like it). Based upon this limited experience I agree that the Caiman doesn't feel exactly like the others. It cocks more smoothly and I think the trigger is a bit more consistent. It is not more accurate than the best of my P35s, however. Both have given me one and only one 200 on the 30 yard challenge. A better shooter would have gotten more, I'm sure. But my point is that at 1/3rd the price a budget gun can equal a more expensive airgun in accuracy. A Stoeger Bullshark is almost exactly the same as a P35 and more widely available. With an inexpensive printed moderator they are very backyard friendly and they are not very loud with the baffles they come with. But the baffles shift and get dinged by pellets so I think a moderator, especially when they are so reasonably priced, makes them a no brainer choice. A P35X is a similar gun with a longer barrel, a much bigger plenum, and a wood stock. The Bullshark and both varieties of the P35 are made by Snowpeak (aka SPA). SPA also makes the Zellos the very similar M60b and Notos. I think the Zellos is the only SPA airgun with an externally adjustable regulator. The others all have regulators that can be adjusted but some disassembly is required. On the other hand, the hammer spring of my P35s is much easier to adjust than the hammer spring in my Avenger. The main reason I prefer SPA guns to my Avenger is they don't use plastic to support the shroud and seem to generally use better materials overall. I think I saw a review the other day of a higher priced PCP with a plastic trigger but in general better materials also seems to come with a higher pricetag.
So, in short, I suggest you look at the M60b, Zellos, P35, Bullshark and P35X. All are in your price range new. I am pretty sure you would enjoy any of them.
