I am considering the purchase of an iGUIDE system. I have been doing RE media part time for about a year now. There has been little demand for 3D tours in my market. I am impressed with the iGUIDE format of floorplan and 3D tour rather than the dollhouse. I will need to develop some demand in my area. I think I can do that considering all the advantages of iGuide. I already own a Theta Z1. My question: Is the $1100.00 upgrade to the R! worthwhile at this point? I appreciate your thoughts.
