From what i have read i am not 100% sure that you really need coilovers. Also since its an everyday ride you must be really aware of the compromises of such a kit (unless you buy them with softer spring rate). Another point. If you have plans for something better (or of more known brand if you prefer eg tein, trd) then again buying a d2 or ksport will be a waste of money (though i think you wont really change them afterwards).
So my opinion is, to move into another suspension mod suitable with coilovers -such as rear arb, anti lift,new bushes esp if you havent done for a long, camber nuts/plates, a bit stiffer spring rates etc- and postpone coilovers for later (since other mods might satisfy you equally for less money).
In case you really need coilovers/your current shocks are dead buy the one you can find cheaper since they are probably equivalent kits-if not same with different color- though d2s are a bit more known.
