Yep. I have one of those universal mounting brackets for the Chief mount which works perfectly with the RS2 (or any other PJ you end up getting down the road.
Hope I didn't offend with my heavy-handed rant against digital key-stone adjustment. For someone just getting into front PJ there are a lot of brand-new concepts and terms that never really factored into the world of direct-view displays, so there's a lot to explore.
One thing you'll notice is that if you have any classic 2-channel audiophile tendencies, front projection is a lot like high-end audio listening. Things like "separation" and "air" and "layering" apply metaphorically to high-end HD projection as well. Subtle differences that don't impart any distinction on small screens suddenly make an "emotionally compelling" difference on your projection system... things as elemental as the scaling chip in a BD player can make or break whether or not you can really enjoy a DVD movie. Also like 2-channel audio, the quest to improve video fidelity gives a thrill factor... as does having your movie loving friends and family say "wow, I thought I had seen that movie before but I never really saw it until now on your projector". That last statement is especially true for the legions of "movies" that most of us have only seen on television/DVD... have you seen Lawrence of Arabia in 70mm? Or seen The Sound of Music or The Wizard of Oz projected properly in a theater from a archival-quality print? Finally, Blu-ray and home projection allow many of us to finally "see" movies that we never really saw before.
