Most gaming mice work well for 3D work. The main reason for this is that gaming mice are built to be precise and comfortable to use for long periods of time, which works out nicely for 3D as well. I've used a Logitech G5 for ages and it's a joy to use. I would recomend anything from the Logitech game series in a heartbeat.

Another alternative that works surprisingly well for posing and modelling (and OFC sculpting) would be a tablet. Its much more precise then any mouse/trackball and many models these days come with multitouch so you can basically use them as a full mouse replacement. I use a Wacom bamboo for this which is excellent and not too expensive.

Space navigators I dont like. I had to use one at work once and I found that I kept having to juggle 3 devices with 2 hands which got old really fast. YMMV of course.
