It really is not that difficult if you (or someone you know) puts a little effort into it. Frankly, I look at the price differential and think "this is a no-brainer to at least try." And just think, 6 years ago it was half the price. Compare that to what it costs to try out some others...$6K for the first "provider," and we'll give you a 50% discount on each additional! That's $3K each. You could just get AC for 3 providers for $3K. And spend less money on hardware to operate it... start off using your existing hardware (if any). It may not run as fast as you want, but it will probably run OK.
I'd say if you can buy a copy of MS Office and install it yourself on your PC, then you can probably install AC by yourself. If there is an unexpected error, call tech support. So do it on a weekday, perferably in the AM just to be safe. Really, the tech knowledge to install and use AC is not what should hold you back. This should be a reason to pick AC over other systems.
