If you can give tight purchase order , and mention clearly what ou, i suggest you to ABB BAiley, INFI 90 , with Conductor NT ver 4.0 and two primary sevrers.
Further to you can go advanced versions like Operate It and SQl servers
You are putting the cart before the horse (that is, doing things backwards). You evaluate systems based on your needs, not on what they have to offer. Think of buying a TV or stereo. You have a set of requirements and then see which systems match those requirements at a price you are willing to pay. If you tried to evaluate them ALL based on technical merit, not only will you waste an incredible amount of time, you might still end up with a system that doesn't meet your individual requirements.
