I dont know how much you weigh, but if you get even a reasonably priced wheel it should last for years. Im only 140 but have toured a fair amount, so in the end you just have to get a wheel that either has spoke count or overal build quality and so what if it weighs x amount of grams more than a lighter set, if you dont have to worry about breaking spokes then it would be worth it. If however you want to save x amount of grams then thats your call.
All the best with your rebuilt wheel. That is something I would like to learn one day.
I'm 250lbs, complete masher, race traffic standing on pedals and love to rock the bike - all bad things for rear wheel spokes. Thanks for the wishes on the rebuild - I'll have to keep people posted on the appropriate thread and share my tips.
