Don should be on here shortly. He keeps a supply of both Sky Raiders and LA Racers in stock at good prices. Only the 'raider comes in solid colors at this time. However, the decals on the LA Racer can be stripped off in a hurry so you can decorate it any way you like.
Your local hobby shop should also be able to get them. They both come from Airborne models.
You might PM Don regarding prices and shipping.
