Wheelbuilding / Wheel Building / Wheel build help

Because at the mo' it doesnt really solve anything doing that, my 9x100/9x135 standard bike already has wheels and until I stop falling off it, it doesnt need anything better than what it has :o

So it'd still be the case of a set of wheels sat about. If I order today though the cheapest I could get the adapters for would be 70eur from the US.

I'm just kind of mulling if that's money well spent or not. I'm a bit of a hoarder, recoup the money now and spend later on something - possibly just as good - or keep on hoarding if they're really that amazing, is what I'm wondering.
