where can I get OEM crossbars for 07 xterra online?

I have searched all over for this part and can't find it anywhere.
Any suggestions?

Some links I have that may pay off:

they're charging 112-150 for the very same things at the dealerships here. that is just sick profit to me. I know these things don't cost that much to make!! I am all for people making a living, but come on!!

Steal these.......
