Need a new drive shaft what is everyone using

My drive shaft has a wicked shake and I was wondering what everyone is using for shafts. The local shop i was going to have do the balancing said they would have to install new u joints in order to balance it properly. So I went ahead and installed a new set. They are 7260 u joints (315G NAPA). Brought the shaft to them and he said it wouldn't balance because of a dent and a missing weight. They wanted 180 plus the cost of the tube. There is a shop in Sioux Falls called drive-line specialties that everyone seems to recommend and they will do it for 125 (price includes the tube)

The engine makes a little over 400hp 2800 stall full manual, 8 3/4 3.91 suregrip. I race it at the track with slicks 2-4 times a year.

Drive-line specialties originally suggested I go to the 1350 u joint. $250 would include the new front yoke, new shaft but I would still have to buy a new rear yoke.

Don't really have the much ching laying around but I would rather not waste 125 putting a weak link in my build.

What do you guys think 7260's with a new tube good enough.

I was also looking into u joint girdles for the rear yoke. anybody using these http://www.jegs.com/i/Moroso/710/85850/10002/-1
