Ed does,nt cater for your "average micra owner" tho eh, and there is a big market for them because of the lack of aftermarket stuff availiable.
personally, i would have concentrated on the panhard rods, offset bushes and strut braces etc, trying to juggle with too many balls in the air is tempting fate.
and i would have made sure there were many items already built/in stock, so that there was no waiting times involved, and like you say, no credit/multi payments crap
