Stataframe has a live demo on their website. It takes about an hour to sit through them but it gives you a good feel for how their stuff works. Also don't forget to look at any other tools you are using. MM does work with infragistics controls, telerik controls, vistaDB data and others but not much support for MS Access data. Strataframe has support for Access data but maybe not some of the controls.

I would write down all the comparisons of these and take that into consideration based on what other things you use or expect to maybe use. Just another data point.
