The best thing too do is if you want too save/test, just order this item on ebay....any model..they sell cheap on almost all websites, just remember to save the box, the manual and the packaging. Ebay gives you 30days ''buy back guarantee'', if you don't like it, contact ebay and tell them ''your not satisfied'' and return it. Just reurn the item the way it came.....manual, box packaging, new.... And your be credited back to your card. Pay attension when you buy things..., the return policies.....!!!!!!
