I have built this kit. The Zaku resembles the old version of the kit--that is, not very detailed, but the Type 61/M61A5s are fun little kits in thier own right. The barrels will need to be drilled out, which I did with an exacto-knife.
results:
sorry about this next pic, it's the only I have of my Zaku (in Progress pic):
and for comparison, a Perfect Grade 1/144th Zaku:
So, you can see the difference in detail. Although the Zaku is really fun to build and detail, I prefer the tanks themselves, since they are little gems on thier own. By the way, the Explosion pieces included to show the tanks "blowing up" are fiddly to align and wouldn't sit flat on the tank, but add a fun bit of detail to the kit.
Best of luck, and post pics soon.
