First time posting so bear with me...

I'm looking to start buying the components and speakers for a home theater system but really have no clue on cost or brands to steer towards/away from. I don't want to break the bank on this, but if it's something that will last for a good 5-10 years I'd be willing to go up to $3K. (again, no clue on how long the speakers last etc.)
Would like a 6/7.1 receiver but dont necessarily need more than the 5.1 speakers for right now.

I currently live in an apartment (living room is 12' x 13' but not enclosed) but would like something "good" enough to move to a dedicated home theater room when I purchase a house. (hopefully within 2 years)

I'm going to be using it mostly for DVDs and TV but want to be flexible enough to throw a CD on.

Any help or suggestions would be greatly appreciated. Thanks!
