Frankly I have built one of ther kits (PAK 43) and I have an other on my shelf (RSO). I checked the RSO, and it has lots of details, just like the PAK did. Really, there's no problem with the amount of details, and these kits are quite accurate as long as I can judge.
On the backside, the parts require serious cleanup. These are "short-run kits" - I don't know what it means exactly, but I can tell you that there are lots of molding seams, shrink marks, and with the PAK I had a few fit problems too to work out. This means much work, but it's worth the effort.
You know, in Braille scale the choice of good quality kits is very limited. Dragon, Trumpeter and Revell make them, but they are all Panthers, Tigers, 251's or some other very common armor (with a very few exceptions). If you'd like to build a softskin, an artillery or a less popular type of armor, you'll have the kits of the short-run companies, like ACE, UM, ICM, MAC...
