As far as I know a TX200 clone was a Chinese B40 (out of production). But Crosman has a Bemjamin Mav77 made by the same Chinese gun factory with said to have a few changes. Was announced a couple of years ago and still not on store shelves.
Chet,Regarding the 9" barrel and power. A springer does not generate more power from a longer barrel a la firearms and pneumatic airguns. So the TX barrel does not hold it back for power. The TX 200 shoots around 15 fpe stock which is good power for a springer but not so much to make it hard to control.It is possible that the short barrel is an advantage for accuracy. The sooner the pellet exits the barrel the less influence the rifles recoil affects the muzzle.The TX 200 is popular with field target shooters because it is highly accurate and powerful enough to have a fairly flat trajectory in .177 cal. The flat trajectory helps the shooter to score the target at various ranges between 10 and 55 yards. I also read that the tx 200 is most popular and winning est rifle. i am not sure of the rules in the game, I know PCP are very accurate, can they be used in the same class, if so, is the tx 200 as or more accurate then say a Maruader.The BR shooter, on the other hand, probably has more interest in bucking the wind than flat trajectory. A heavier pellet (.22, .25, .30 cal?) may be a better for tight groups outdoors at any given range.My .02 would be to get the TX 200 but I have never had one so take my advice with a grain of salt. I 'll bet your Disco could compete in the accuracy department with whatever spiringer you end up with.HTH,Mark N
