for a cheap crankset i would probably go for this... i don't know about the one you linked but the price scares me! the stronglight one is also very cheap and dunno how long it will last but atleast its a known brand and they are used on some off the peg bikes, i think brompton? velosolo also sells them and has a deal with matching bottom bracket if you buy from them, but it is a bit more pricey than ebay.
