There's a lot to be said for SLS printers, if you can afford them. The powder bed provides support, so you don't have to worry about adding it or removing it later. Detail is good, and any configuration is possible. Plus, the models are stronger across the grain than FDM parts, because the layers adhere to each other better.

The multimaterial Objet printers are pretty nice as well; you can make things that are partly rigid and partly rubbery.

But it really depends on what you're trying to produce with these printers - what would that be?
