I have the Tamashii Stage stands. I prefer the Act 4 ones becuz it has the
two pivot point arm thing that is longer than the Act 5 and just as solid; the Act 5 arm is too short. While I've never used them for TFs specifically, (I do use them for Bandai products like Gundam and Kamen Rider toys they are marketed for) I can tell you, they do the job very well.
The Quakewave stand is so good. It makes the toy look like a prop replica of sorts. I enjoy it so much, I leave it in gun mode most of the time.
For anyone wondering, the stand is made by this dude on ebay. I assume he still has some to sell, but probably in limited quantities and colour options.
