I want to buy a scorpion, what kinds are these?

I am trying to find a scorpion to purchase in the near future, and was looking online and came across these, yet I dont know what kind they are. If anyone can help it would be much appreciated

at a guess, the middle is P imperator, though it's hard to tell, it may be a Heterometrus, and the third might be Androctonus or Parabuthus. no idea as to the top, but i need it!!!

edit: the more i look at the middle one, the more it reminds me of my H cyaneus...not cause of the blue mind. but that could be way off!

First is a Hadrurus sp. photographed under just the right light to make it look more awesome than it really is . . . it's come up before.

Second is a Heterometrsu sp., probably H. spinifer, photographed with a flash that had enough UV in it to make it come out green (same effect as natural sunlight).

Third is Androctonus crassicauda, NOT for a beginner.

When you're starting in the hobby, the absolute worst way to go about picking your first scorpion is choosing the one that looks the prettiest.

surely that Hadrurus spp couldn't look that much worse in normal light?!
