With a budget like that your looking at very basic morphs(not thats theirs anything wrong with them). Your looking at yellow bellies, pastels(not high quality ones), larger normals, Hets for either ghost or albino. and thats about it. Is $150 for everything(cage,heating,hides etc)? or just the snake alone. If you are looking for females i would say look at a het albino(or ghost) or a pastel, there will always be plenty to morphs revolving around pastels/hypos. Or what you could do is save up a little more money and just get a banana. then you would make everyone on here really jealous.
