Snap, i forgot to mention, atv discounter gets mixed reviews, make sure you get them ON THE PHONE before you order.
I've heard they're hard to get ahold of through email.
When you talk to them, be sure they can send you an mso/mco, bill of sale, and/or whatever else your state requires for registration.
You should be able to search your bmv/dmv website or call your local dmv/bmv office to see what is required.
For instance, here's the ohio imformation
