Welcome, tcastrinoes!!! You have chosen wisely in your move to Klipsch.
Are you looking for new speakers, used speakers, or either?
What cabinet finish do you prefer?
What is your budget?
What is your in-ceiling application and room sizes and configurations?
Another really good "bookshelf" speaker you may consider is the RB-5, depending on answers to questions above. I believe Michael Colter (colterphoto1) has a beautiful pair of maple RB-5's for sale. He may also have some other pieces that may interest you.
Enjoy the journey . . . . .
