I'm partial to my own bitone finish, so if i wanted to pick up an sc i'd probably go witha matching bitone for that as well. Both for ease of maintenace, and i just think it looks better.
As for your night sight v. tactical light dilemma i would go wtih the night sights. you can always get the light after with much more ease than you could the night sights. I would rather get the night sights put in at the factory rather than put it in myself as i am unexperienced. However, another incentive to wait on the tactical light may be the fact that the new X2(xml2) light from insight will be released soon. That gives you both the practicality of a light as well as the added feature of the laser.
just my 2cents.
