First, seach past posts as it manytimes has your answers.
Last year I bought my son a Kasea Skyhawk 90.
This board helped me make that intelligent decision. I'm happy that I did. 1 year later, and with exception to a dead battery (my fault, left it on), it has worked great and my son LOVES it. Very much worth the $1800 out the door I paid.
And it's a dead ringer for a Honda 400EX, so the looks are equal to it's performance.
Kasea is built by Standard Motor Company.
