Almost all of those entry level flip-flop hubs are identical, they're just branded differently. It's only the Miche Primato which is different with its solid flanges. If you're buying a pair and spokes, by far the best place to get them from is
http://www.cyclebasket.com and their stainless double-butted spokes are exceptional value and strong. My Zenith hubs came from there and I put around 11,000 miles on mine over 5 winters in all weather before the bearings needed replacing.
The hub will basically go on indefinitely. You just replace the bearings with a standard good quality 6001 2RS size bearing. You can just relace it with new spokes when the spokes or rim die. I don't know what you would have to do to damage a hub tbh, they don't crack or dent these days.
If you want better quality then look at the Miche Primato and Sturmey Archer ones, above this you've got Dura-Ace track hubs which are up in the £150 region and above that there are probably Campagnolo track hubs for £lol. To be honest though, the only difference between the entry level ones and the Sturmey/Primato is the look of the hub. The Sturmey is a much more traditional looking hub
