How bad you want one? If real bad and seeing how people now selling them for £50 - £70 on ebay it might be worth taking the risk. You could always buy one from a local store where you get to see the product and it's full specs.
I did the same with a HP 1260i which I bought from my local PC world store just to test even though my first iHas 124b drive is working strong and also I got a spare one sitting on the shelf.
