In need of a new power wheelchair.

In desperate need of replacing my scooter with an electric powerchair. The scooter has been good to me for about 2 years. However, it died. I require a power chair to keep up with my son. Insurance will pay 80%, but i have to come up with the other 20%. Please help me keep a smile on my sons face. Any donation helps.

UPDATE: Insurance has finally approved my chair. We have been saving up and are now only $600 more from our copay!! Thank you everyone for your help!
