Nissan stock but will most likely cost you more then aftermarket.
TEIN Super Streets are suitable, Height adjustable for daily-(driveway) or drop it for a cruise/spirited drive. Also can soften up damper so not too harsh a ride even though it aint too harsh when set stiff.
They retail for around $1500
Or if you are after decent 2nd hands give me a PM, My mate has some which he took off his car, they would of had approx 50,000km of use.
