This started out of my own desire to find who sells what? Froggle just wasn't hacking it for me. I'll probably drop it at the end of this year. It's only a starting point.
Straight Shooters isn't the only dealer to do some prep work before shipment. However, the SS website can't be beat for good information. I spent days reading most everything they had about airguns. The sad state of things is that they have more information than most of the manufacturers! SS also hosts a very active chat room which is also a good resource. For all of that, including their prep work, I give them a 5* rating.
The chart is more of a starting point to see who sells what. Of course there are other dealers who don't list their prices on line.
Good shooting.
