Ok, well your objet edan printer 500V is a fine printer, one of the best infact - when used on high quality mode, which most of the time you don't, so this causes awful stepping in the printed models (on high speed mode) which I find completely unusable (I print 1/6 scale and smaller - so I have to resculpt back into the model) as it stands, when you switch the printer back to high speed mode I have to use www.moddler.com to print my models (slightly cheaper and is always switched onto high quality mode)
Anyway, high quality mode or not, miniature figures just don't print out well because of the stepping. Projet hd's (which prints in acrylic) is another good solution, it prints at a slightly lower layer thickness of 0.045mm with much less stepping, but is expensive, and the perfactory prints at a higher layer thickness (compared to your objet edan's high quality mode) at 0.015mm and has a higher resolution as well - but this is reflected in the price and is just too expensive (from the companies I've found who use it) for larger non jewellery type objects. So this leves me with the solidscape wax printer which prints at a higher layer thickness than all of these printer and has a much more reasonable price tag to it (at www.cadjewelrydesign.com) which will print my figure (a 75mm figure in this case) with all of the detail, no steps and no prep work (priming and sanding down and then realizing that most of the detail is gone!!)
and if you want any more reasons just look at this model produced on a solidscape -
