I just started building this kit and so far I'm quite happy it. I've compared it to the Tamiya kit and while no one can really touch Mr. Tamiya's team for the fine quality of their casting and surface detail, I actually prefer the DML kit. I think the DML turret is a bit beefier looking than Tamiya's. I also like the individual link tracks. Even though eack link has two knock out pin parks to sand off, they really clean up easily and quickly. Tamiy's kit has the workable suspension but I find that of little value. The DML kit has some small detail that Tamiya's is missing, like the front and rear fneder braces and individual handles for the fender-top storage boxes. You can probably pick up the DML kit pretty reasonably on eBay too, since many modellers have rushed to add the Tamiya kit to their stashes.
I know that's by no means a difinitive review but hey, I just started building the thing.
