Jeremy,
If it's just your factory mast that's messed up (plastic guide on inside with teeth), just buy a new mast if everything else is ok. Toyota parts dept should have no problem getting one for you. It's not "too" hard to install it, just be patient, take the motor out and do it right. That's what I did.
The factory antenna is much better, quieter and smoother than anything aftermarket...even the Harada.
