gruntball appears to be one of the best places to get anno..but i'd wait until you have a few things to get painted. Usually places that do the paint jobs will give you a little bit of a discount if you have a few things done at once..plus IMO it's a nice thing to have your gun and kit annoed the same. Just looks real nice..
Other than that, man.. I wouldn't let "color" stop you from buying the scepter. It's a VERY nice kit. I own one and I love it..although I wish I had the 07 front instead of the oldschool one. I think it'll be a little more accurate with the different style porting.
Gl, bro. Scepters FTW.. (pepperstickz are awesome too!..lol)
