Stanley: You really need to check out PMMS mate

The Tasca M4A1 is certainly the way to go, but the Dragon version is one of their newer kits if I'm not mistaken and should be pretty on the mark.
As for the MiniArt Dingos, well... you really don't need any reviews mate. They are literally such crackin kits that they've sold out like hotcakes since their release. Just pick the version you want and go with it

The T-70M is quite the model too, and has been made available in many releases. Best T-70 out there that I know of.
The Dragon Tiger II's, Panthers, and Panzer IV Ausf. F2 and J are very good as well.
If I remember correctly, Darren said that the newest Trumpeter Chally 2 has refined drive sprockets, but check with him to make sure. The fidelity of the Trumpeter Chally 2's is much higher than the Tamiya offerings.
Again, PMMS should cover most of the reviews for your list there
