Rocker arms are typically a market that gives you what you pay for. Check out the array of stud-mounted rollers that are being imported from off-shore! It's only a matter of time before you'll be able to buy shaft-mounts as cheaply. You may wish also to buy your milk in China while you're at it? They'll probably be willing to sell it cheap now that the consumers have learned the meaning of "melamine?"
If you use a small cam, low RPM, and light spring pressures, you might get away with budget rockers. The cam you describe isn't particularly radical so you may wish to roll the dice. If you decide on something a little more aggressive you may be spending the money all over again.

I recently found T&D Machine Products rockers. Anybody using them? They have internal oil passages that lube the tip and spray oil onto the spring. I'll bet their costly tho...

Contact DRE Racing, they are one of the very few that acutually use billet to make thier rockers instead of formed or extruded aluminum.
I have DRE's on my street car, been flawless for 3000+ street miles. After my initial adjustment I have checked them 4 times and they have been either in adjustment or VERY close.
DRE also has an option for spring oilers to help the springs last under very high lift, high rpm applications, it oils the spring out of the front of the rocker.
As far as the Yella Terra's I have heard more bad than good in the LS1 world, got a buddy that is on here (ATLSS) that has a head/cam LS1 with them on there and one broke in less than 3000 miles.
