Open division guns typically go from $3k to $7k for a Limcat. you can find used from 2.5 - 3k. I got mine super cheap around $1.6k as it was an old gun built more than 10yrs ago.
The reason it choked was because of the extractor. it was a little too long and started hitting the barrel when the slide goes forward. it made the extractor jump off it's path and loosen it's grip on the shell case. it's fixed now and will run fine
Open Guns are like Race cars, they need constant care and maintenance to operate at that level of performance. that's why they call it Race Guns. btw, all guns choke, even plastic fantastic ones!
hope that helps!
