Purchase/Prebuild - What's the difference?

[Billfred]

(resists the urge to go off-topic)

By purchasing, you've got a finished Billfred Industries gearbox, which you know you can mate up to a kit motor of your choosing and rock.

By building in advance, you've got a challenge. It may not look as pretty as the BI gearbox, it might not be as cheap, it might not even work for a couple of months. But when you've sorted it out, you've got a gearbox that you know works for you. And while everyone else is using Billfred Industries gearboxes, you're going to get lots of cool looks, respect from everyone who's tried it before, and perhaps the odd comment...
