You will be better off in the long run to just change from Scottrade for all the reasons just mentioned.
I've been with TD Ameritrade for several years and have never had a problem. The level 2 and the Think or Swim platform you get with them is worth it alone.
You can have your stock transferred. TD Ameritrade will do it upon request once you open an account with them. I do understand though you may be reluctant to get caught moving your stock when the short squeeze happens. Just ask TD how the process works.
