For me personally, I did try the opensim grids, and not all are what they advertise. When choosing one must look at the technology in place. Does the new grid have what my business needs to grow. Does voice work, groups, search, classifieds etc. There are grids that don't have these in place making it impossible for you to establish your business. I have found a grid that has everything in place, and virtually no lag. It amazes me people would rather pay more for SIMS in SL. Virtual Highway offers, less lag, less expensive SIM costs, for less than the price of a SIM in SL, in Virtual Highway I have 11 SIMS for 200 USD, not all are full region but it is just an example of the opportunities available.
