Hey guys

I just realized that I dont know anything about boas. I've heard about Boa Constrictors, Imperator, Central American and few others. Are these the same?

I just want a regular boa (no morphs such as albino) since I love the colors. I've looked online but almost all sites don't offer "regular" ones and all the prices are 300 and up, while petco offers one for 150. I handled it today and the poor thing freaked out and tried to get off me so fast I had to put him back in his tank. Are boas generally more active and faster than ball pythons?
