First of all - this is a professional piece of software. With a price to match. In my opinion it is worth it. Every penny (or cent). Had some problem with crashing using the time-lapse function when hooked up to my HDV-camera, but the developer sent me a new version to try the next day. The new version works like a charm!
It is a bit of an resource hog, and it spends its time around 100%+ when doing time-lapse, but it don't seem to slow the computer down, so I guess it uses as much as it can while still being a good citizen. When doing stop motion it's very efficient, and has a dark theme - perfect for use in a studio to prevent to much spill from the screen. I haven't tried all functions yet, but provides all you need for animation, including x-sheet, audio, time-lapse, cinematography functions and multi-exposure shooting. And, yes, it is perfect for (and I guess made for) use with DSLR. With some cameras (as of now, Nikon and Canon) you can control everything from the application. If the camera has LiveView it will use that. If not, you can attach a videocamera to get a live view of you scene. Oh, and it comes with it's own controller with a 10' (or 3 meter) cord.
So, all I can say is - download it, spend some time with it and you'll love it.
