The user interface is highly modal, which is a bad thing, but show me a 3d package that isn't initially confusing. Once you're over the extremely small hurdle of the modality, everything else is extremely easy, intuitive and well laid out. From the end of the market I can afford, I've tried this, Carrara and AC3d — this blows the other two away and I highly recommend it. It's probably worth three or four times the price.
