I saw these in freestuff and thought they looked very nice, but I didn't download them, firstly because I have no way of reading .max format, and secondly I don't have any particular need for such models right now, and while that often doesn't stop me downloading things just in case, by and large, I suspect if I really need a spaceship in the future there will be something somewhere I can download that will be suitable, or I could make something myself without too much difficulty. So you can deduce that if I don't get them when they're free, I'm not likely to buy them in the marketplace. This is no way any criticism of the models themselves, which look good to me. But definitely not commercial.
