Chainrings that are ROUND!

Chainrings that are ROUND!
Is there such thing as a cheap chainring that is not to far off round? Im still fooling around with ratios and im not looking to drop a ton of money. Please soothe the inconsolable rage with your experiences and suggestions.
Edit for 2/16/11 summation:
-Blackspire agreed by multiple online persons to be a sure fire bet for best quality for least cost.
-Origin 8 older thicker model chainrings are cheep and steezy for the least cash, but allegations of cheaper and thinner new models.
-Rocket rings are claimed to be hideous when mounted 130 but cheap and round.
-Higher cost rings sugino,miche, etc provide reliable quality.
Paraphrased words of wisdom from M_S:Swallowing your pride and not running a super tight chainline will be more forgiving to minor variances with little cost in performance and wear to average users.
Also be sure to rotate your chainrings: https://www.pvdwiki.com/index.php?tit...ing_Chainrings

Working on a trash bike with the riveted three ring setup. Gahhh...Nightmare. Still, just off enough for a little chain slack/tense wobble.

I've learned to swallow my pride and run a relatively slack chain... at least by some people's standards. It runs so much smoother.
I guess that was unsolicited. Um, two different 130 BCD Suginos I've bought have been nice and round. 46 and 42. Hope that helps. I also have a 44 rocket ring that isn't perfect, but it's not bad. I gave it to my roommate because it was ugly as sin using the 130 BCD bolt hols, with the 110s just kind of hanging into space. Way hideous. Like this:

Heinous.

Standard.
That said, Ned Overend I think was using an elliptical rotor q ring on his singlespeed mountain bike. I would imagine his mechanics wouldn't do such a thing if it made a difference. So you can get away with a lot if you don't insist on running a super taught chain.

Sugino messenger is perfectly round, and strong under peddaling force, which is another important note.
