New headset buying advice

I have lost my iPhone 3G headset somewhere and now considering buying a new one. Well, I searched online and found a Newegg discount deal on Macally Premium stereo sound hands-free headset at NO LINKS They are offering this headset for $39.99. I don't know about this brand, so confused about spending so much money. Does anyone has or used this brand? If so, then what's your experience so far? If you have any better recommendation, please let me know.
 
Thanks..    

Hey, i-phone is awesome gadget , I too own an i-phone. I am enjoying with it , if you wish to purchase one, then I suggest for a brand new. There should not be any compromise with quality.

Without it, you won't be going anywhere. Yes, a bike headset is an often-overlooked but, oh, so important bike part. Of course, there are several types of bicycle headsets available, so in order to assist you in making the best purchase possible, we've put together this headset buying guide with some detailed, helpful information.Threaded vs. threadless headsets.For many years, threaded headsets were the only type available. They require the fork's steerer tube to be cut to an exact measurement for use with a specific frame. The use of a threadless headset allows for greater adjustability and fine tuning in order to achieve the perfect fit. For this reason, threadless headsets have become the norm in recent years.
