Added on March 8, 2011, 7:52 pmThe condition is 9/10 sc is about 13k he say he need to sell it asap to fund for dp for his cars
Let me list out
some for you then...
Advantage of D3100 over D90:
1. 14MP instead of 12MP, but nobody really cares, so do I.
2. In max resolution, D3100 10min video recording, D90 only 5min. (I still can tahan with this

)
3. Full HD video recording + can AF! D90 not Full HD and cannot AF while taking video. (I'm sick of this!

)
4. In Live View, D3100 AF waaaay much faster than D90. (I'm very sick of this too!!!

)
Anyway, it's still your choice. My opinion, go for D7000 instead
