My stage 2 that i had to send back cost 350 to be rebuilt.....though i found the turnaround time terrible and the bullshit they gave me on the phone every time i asked when it would be back a little annoying!
I already had one of their boxes so figured it easier to just send it back to them so just had to swallow it, and they didn't even change the end casing seal so the bloody thing leaked lol
