Looking to buy/rent time in an AX Environment for Practice

I am taking several Dynamics AX Financials eLearning courses.  I am looking to buy or rent time in a Dynamics environment so I can practice the exercises in the eLearning material.  Microsoft's eLearning training courses don't give much software to pratice the configuration exercises that the courses explain.  So far, a lot of the training material is mostly lecture.  How can I really learn this if I can't practice it?  Amazon.com's cloud service rents out an SAP HANA environment for people to play with.  It's basically a sandbox.   Does anyone do this for Dynamics AX 2012?
