This is the one I use. However, it was just the cheapest one I could get from that place, and I was buying other things anyway. I know that with one I bought cheaply off Amazon it was a dud, so I would recommend actually getting one from either a shop, or a website which doesn't allow other sellers (so eBay and Amazon marketplace aren't the best choices).
