The Orion and similar lasers are not well enough collimated internally for RCs. Don't use it! However, there are many ways to collimate these things that don't require you to buy the expensive lasers. My recommendation would be not to touch anything until you get the scope under the stars and do a star test. The scope may come adequately collimated, and you don't want to mess it up in that case. Your experience with the Dob will not help you here; RCs are much more complex to collimate. Just search the forums here on collimation -- there are many, many threads on this topic.
