well, personally if i were buying a spider i would go with a male, just because you can breed a male to 5 females. that is alot of spiders to produce. But with what you have right now, i'd buy a 100% het albino female, and a few more normal females.
then you could start off by producing more pastels and you could then keep all the female pastel's and use them to make designer morphs, and then make albino's also.
