I assume you're American. The One80 darts on Amazon are REALLY nice and they have many different models. I highly recommend Style H.

They also have these darts which are an awesome set of darts. Long story short... Red Dragon and Winmau are basically the same company and those darts are actually the Winmau Navigator 3.

Now with that being said have a read of this article and then after reading that head on over to Darts Corner and look at the Designa darts. I would HIGHLY recommend the Designa Patriot X darts or even the Darts Corner Gallant darts. Both 90% tungsten and right around $20. They're as nice as ANY dart on the market regardless of price. Also, don't ever let anyone tell you that expensive darts are "better". Darts is one of those oddball sports/hobbies where price has absolutely nothing to do with how "good" a darts is. Like you said, it's just marketing crap.
