Taric,
What kind of budget are you on?
If you are looking for a Valkyrie that you can put up as a display, then you really should look at Yamato. They have decent detail, and have above average durability. The 1/48th scale editions have excellent detail and above average durability. You also need to get a bank loan to get one
I'm not too familiar with Takatoku or Bandai. The closest I can remember having to them was a Transformer toy called Jetfire. If you want a toy that you can rough around with, go for one of those. They are relatively affordable, and the quality isn't too shabby.
hope it helps...
