Realspace Models has just released a new resin kit of the Ares I rocket launch vehicle, with 2 Orion versions available. Lunar and Orbital. The price is $75, though steep, it is for now, the only available kit of this subject (LVEH). Until an injection version comes out this is it. I have built kits from him before, and his kits are usually very detailed and worth the investment.
