Thumbs up for Cowboom.
Last time this deal was offered, I decided to give it a try because the price was so low. I figured if I got a bad console, I could just file a dispute with my card.
My console came within 7 days after placing the order, and although the console was dirty, and in much need of cleaning (had to wipe down smudges and use compressed air on the vents), it works perfectly fine. Thoroughly tested for about a week with Blu-Ray movies and games, and no hiccups at all. The only slight problem was I got a defective controller, which Cowboom refunded me for. By the way, the website makes it seem the return policy is 15 days from order, but its actually 15 days from receipt.
However, I read others had problems, so YMMV. But my experience was very positive.
