I finally got my DME to bring some chairs out to demo. He didn't have an E-Motion to try but did bring out the Quickie power assist version. I am amazed at how easy this device makes using a chair. I may actually be able to go to the bathroom now by myself without asking someone to push. Wow, this may really change my life. I think I am going to go with a Tilite Aero Z. I would appreciate any recommendations on options I should look at for this chair and if anyone has any comments on the E-Motion wheels. Now I just have to get my insurance to agree. Thanks again for everyone's help.
