Not very happy with Cycle X at the moment, for upon telling them that I need the correct tubes by friday, they charged me 25 bucks to ship the tubes 3 day mail, and it is saturday night and I got nothing. Again, re-ordered on tuesday morning, 3 day air, and still have not received my tubes late saturday night. Particularly concerning because I am moving in 5 days and NEED to finish up this build so that I can pack up my garage. Really lame.
