Recently my MBP died

, (wouldnt start, black screen, white light on) searched the net, consensus was bad RAM. I have the apple supplied 2gig. took it to apple, turns out it's the connector for one of the ram slots (so it runs with 1gig of ram - for the moment) - anyway it turns out it needs a new logic board.
If i'm going to have the logic board replaced, i think i should upgrade the HDD while the techs have it all pulled apart - so What HDD to get? My priorities are (1) reliability (2) size and (3) speed
