I would just retube it yourself. I'm sure there are a lot of other people on here that would say they don't recommend it but I definately do. I always builld my own drive shafts and then just take them in and have them ballanced. I use a piece of c channel to set the drive shaft in so it's held nice and strait, I bevel the edge slightly and weld it up. I have never had a problem and it will definately save you a lot of coin, plus this way you can go to a heavier tube. If you run a factory one it's only a matter of time before you shred it on a rock. I hope that helps.
