I personally think that headsets under $70 might have its problems here and there.
As for under $40, with the listing at Best Buy, I'd go with: http://www.bestbuy.com/site/Plantro...04379967&skuId=8978403&st=headset]&cp=1&lp=58
or you can try the following for $50: http://www.bestbuy.com/site/Logitec...114294761&skuId=9429861&st=headset]&cp=1&lp=4
Each of them is going to have their ups and downs due to the price, but that's what I can find. If you're not restricted to buying only in store @ Best Buy, try other sites like newegg.com or amazon.com to find good deals.
