I dunno what's your idea of "relatively light", but I'd recommend a Manfrotto 190 Pro or 190D. ~1.5kg excluding the head. It will be more than enough for your future DSLR (unless you are also thinking of using superteles like a 600/4 ).

going to take some grad photos around town and kallang area at night
so thinking of getting a gd tripod once and for all...
guess my bro left that out when he bought the digicam
Maybe u can try the Slik Able 300 DX. Available at AP for $110. Was recommended to me by CP as an cheaper alternative for the Manfrotto 190. Can support up to 3 kg of load. Comes with its own ball head. But ball head can be changed to Manfrotto 352 or 308 if u want. Very satisfied with it. No complaints.
