3D Printer: Invision SR or Objet Eden 250?

Can any one give me recommendations/comments/experiences of either of these two printers (3DSystem’s Invision SR vs. Object’s Eden 250)?

We are considering upgrading our FDM printer (Dimension BST) and have looked a both printers but they both have pros and cons.

Has anyone worked for a while with the Invision SR? We heard rumors that the hardware can cause problems sometimes?

Thanks very much!
