Boas come in many morphs (most much less expensive than BP morphs) albinos run around $600 or so.. they are one of the least expensive morphs.

I would not say that blood pythons are hard to take care of. They are much easier to feed than your average ball python, and they just need proper temperatures and humidity like any snake. A 6' 30lb blood is definitely handleable, however you have to be mindful of the weight, and not just sling it around your shoulders like you could a ball or red tail boa.
