I've had 3.
Still have 2.
TC does not support parts for them and that has been a problem for me. I just bought a used $3 part on ebay for $55.
I personally would not buy another one , just due to the breakages I've experienced and the parts support issues.
A used rifle is worth what someone is willing to pay for it.
Personally, I wouldn't even consider paying $300 for one. Just one man's opinion.
