The CMI International LS-2000 Pro Tournament is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
This gun has a few good features that set's it apart from the others. First the gun shoots very accuately. The barrel that comes with it is a CMI barrel which are nice barrels. You can also not freeze this gun. I tried to freeze it with Co2 and it would not freeze. It is also well built and very reliable.
Here is where this gun goes way down hill. The trigger is by far the worst trigger I have ever felt. I could shoot the Stingray 2 faster than this gun. They say the trigger is all pneumatic which is true however the design of the trigger has made it so that you have to pull the trigger all the way back and then release it. And it is very easy to short stroke. The trigger is also a hard plastic, but the trigger is not going to break or anything. I good maybe get 3 balls a secound out of the trigger but that is all.
This gun is reliable and the gun shoots straight, but the trigger is what makes this gun go down hill. That is probably why no one knows anyone who has one. I have one but when I used to work at a paintball store the owner had 2 but was never able to sell them because of the trigger. I have heard that CMI might make an electronic trigger for them to boast sales, and if they did they would be doing a wise thing.
