For me it depends if she's a steal. Since I already have an enchi and the only reason why I would get another one is if it's a bargain and she would look spectacular then the one I have.
I wouldn't pick her up. I kinda learn my lesson to a certain point. If I ask myself SHOULD I PICK HER/HIM UP? Then end up getting it i feel less desirable after picking it up and having it. Kinda like I should of waited for another opportunity.
If I'm in that mode I gotta have it. It looks beautiful and I do manage to get it. I'm really happy and glad that I did! Kinda feels like I'm really proud and lucky to get it
But the snakes I was iffy to get and i did buy seems to be problematic for me. Doesn't eat to well, always miss couple of meals, etc. Hope that makes sense.
