We operate an Objet Eden 350V at my day job. I have to say that while the printer makes parts that look good and runs lights out there are way too many downsides.
As others mentioned many of the materials are not really up to par, in addition to the problems mentioned they are brittle so you have to tap all screw holes and be careful to not shatter them with force. RGD450 is their best material in my experience but it is also very porous and can absorb a lot of water which will cause warping and deterioration of thin features. I have also experienced a change in material properties over time with the Objet resins as well. I have heard that Digital ABS is a much better material in general but that requires a machine with material blending features.
In addition to those problems the cleaning process is quite tedious. In my experience running parts in glossy mode can be risky for small features. Therefore our machine always gets run in matte mode where the entire part gets at least a coating of support material. The cleaning process involves manually scraping as much material off as possible, then water blasting in a cabinet which is not fun. We then soak our parts in NaOH for 25 minutes and follow up with a second round in the blasting cabinet. The cleaning process is a huge pain for small parts, if they can even make it through the process without breaking.
Lastly, we have not had good service from Stratasys. The techs know their stuff, but there are not enough of them or parts. We have run into some serious problems with our machine and ended up with it down for at least a week before a tech could get there and then we were able to get the parts. Another time we told Stratasys what we needed for parts, gave them our serial number, and parts for a different model showed up…
If you still want to look at Stratasys, the 260VS looks like it has a water soluble support material and some better model materials available. I would get a demo of the cleaning process on that though before I bought it. If you are set on a polyjet machine I would give 3D Systems a look as they use a wax support material that melts away. It seems that it does still require a secondary cleaning operation though.
