I ordered from eCOST.com a few days ago and it was a very positive experience.
They had the absolute lowest price and they shipped it out immediately for FREE! 
They also list live inventory levels with every product. There's nothing worse than finding out your product is back-ordered after you buy it.
They communicated well with emails and quickly provided me with a tracking number to track my purchase.
My only complaint (not a deal breaker) is how hard it is to buy a product from their Bargain Countdown section. If you click the "click & buy" button on their front page, it takes you to the hot bargain area where you have to find the product a second time in order to add it to your cart. Considering the low price and the free shipping, it's well worth it!

A quick update about eCost:
I continue to buy from them and they continue to be nothing but outstanding in service and price.
