The first one is only 0-18% Brix. You are going to want the 0-32% brix, unless you only brew low gravity beers.
Other than that the second one looks good. I bought the cheapest one I could find on ebay, and it was DOA. I got a refund and bought a new one from another company on ebay and it works great.
Keep in mind though, both times it said it was shipping from the US, and it actually was drop shipped from the manufacturer in China, so it took about 2 weeks.
edit: I just noticed the second one says the item is located in Hong Kong, so you should already expect it to take a while.
