Why do you think R is not easy to implement? My company has been using SAS for a long time and we are finally making the change to R. As far as OP's requirements are concerned, I think R is way superior to SAS or SPSS because of its free, modular nature. It is clean, simple and suitable for a wide range of users. The commercial packages are filled with way too much business lingo garbage for me.
I personally think commercial support is overrated. I can install software on my own. I know how to browse through manuals and other information to find what I need. For a package like R, I almost always get any questions answered in at most few hours on online forums. So what exactly do I get from commercial support for my money? But, if OP needs commercial support, there is an enterprise edition of R by Revolution Analytics located here: http://www.revolutionanalytics.com/products/revolution-enterprise.php. Might be worth looking into.
Bottom line: R all the way.
