I'm not an audio system expert, and I don't keep track of the latest deals and specials, so you may be better served by a website like Audioholics, but take a look at www.accessories4less.com at their theater package as they often have some very good deals and have a decent website.

Keep in mind, that many people who just like a good sounding theater will spend at least half of their home theater budget on the audio portion, and good speakers can last for 15-20 years, while a projector typically lasts 5-10 years at the most. So, good speakers are a much better overall investment for long term use and enjoyment.

I certainly wouldn't start with Klipsch reference series as a 'starting' point. Those are well beyond the budget of most, and make very little sense if a entry level setup is required.

Also, a lot of people don't like the sound of Klipsch as they are often a bright speaker depending on the room.

Plenty to listen to if you have a budget for audio in the thousands.
