Sometimes the best option is not always the lightest and if doing nothing more than commuting most would not actually notice the weight anyways.

While true that most builders are happy to rebuild hubs for an extra charge before building wheels, I only mention if your hubs are in good shape because some hubs can get damaged/worn beyond the point that it makes sense to lace them into a new wheel. Specifically cup/cone hubs that have been horribly neglected, especially if it is only a few bucks more than a rebuilt to buy new hubs.
