I just read this post on a Yahoo group.
"Special Hobby: Part of the MPM group. "Generally" speaking: Limited run kits with very nice surface detailing, excellent resin parts, some photo etch, nice decals and sometimes vacuform canopies. Sprue attachment points are sometimes heavy, and many times there are no locating pins (both no big deal). Accuracy is sometimes suspect, but nothing major. Sometimes fit is not perfect and trailing edges are not thin enough. Note how many times I use "sometimes".....
Overall, Special Hobby produce very nice kits that take a little more modeling than say, Hasegawa. I'd recommend them."
Here is a link to a review of their 1/32 P-39. I know it's not the the Mojave but, it will give you an idea of the quality.
