The seams on the old Nitto kits are notoriously... fun(?). The newer Wave kits still have the seams, but they're better placed and tend to "throw together" much easier. Of course, that takes away from the aforementioned "fun".
Outstanding paint work and overall subject composition. The seams detract slightly, but certainly don't cripple it, by any means.
The best spot to order Ma.K. kits in the U.S. is from Starship Modeler--as smeagol mentioned. If you don't mind going international, HLJ.com is also a good bet. And, on a final note, the SAFS has been completely retooled by Wave and will be released in January. This isn't just tweaking the original Nitto molds (which Wave also has possession of), this is all new tooling and an all new kit. HLJ has it up for pre-order (EDIT) and will begin accepting pre-orders soon:
