Welcome. I don't have personal experience with an
ecv. My youngest daughter uses a manual wheelchair and recently started using a power wheelchair.
This is a list of all the places that DIS posters have reported good experiences renting from:
CARE Medical Equipment - 1-800-741-2282
www.caremedicalequipment.com
RANDY'S Mobility in Kissimmee 407-892-4777
http://www.randysmobility.com/
Walker Medical - 1-800-334-9501
www.walkermobility.com
Colonial Medical

I'm sure some of them will post a little more about their experiences. Some people prefer one company over another, but I read all the posts and I would not hesitate to rent from any of these places.
Some people like
ecvs better because you can be more independent. I know my daughter is more "in charge" when she is in her power wheelchair as opposed to her manual one. Some people are a little intimidated at the idea of driving an ecv, but they are pretty easy. There are some rides where a wheelchair can go on, but not an ecv.
