Biphenton vs Ritalin

I had a mini meltdown today and called the doctor!! i go and see him tomorrow instead of next friday!!! So i was wondering if anybody had tried biphenton instead of ritalin? how did you feel on it etc,, I don't want to try concerta until i have to because we dont' have a drug plan and it is very expensive!!! Your suggestions and comments are apprechiated!!
