although i think spiders are nice lookin' my personal preference as far as a spider morph would be the bumblebee & me personally i'd pay more for a high white versus a low white. i dont see it as they're less valuable but i like the lookers more then the the run of mill common lookin' ones. thats just me...
now for the pieds...since they've been brought up...i would try find a medium white (pumpkin pied specifically) with 50/50 white/pattern or as close to that as possible.
my personal favorite in high white pieds though would be the lesser pied but there's no way i'd be able to afford its high price tag.
ok enough about pieds...my point here is again:

i would pay more for a high white bumblebee.
