Its not the money spending im worried about but what is the limit i should pay for a normal ball?
Well...as an example of my personal philosophy on spending money on these animals:
I'd spend $150 on an exceptional "normal" ....but I would NOT spend $75 on a browned-out ordinary pastel or a muddy, wobbly spider.
Whether morphs or normals...if you're intent is to breed, then you want to choose the very BEST examples for your breeding stock. And if you just want them as pets...then you want to choose what makes YOU the most excited about cleaning poop for the rest of their lives. :P Money is really a side issue and of little consequence in the long run.
