I went to one of my local stores and they had F1's for $1099 for the entire set and a Yamaha 365 reciever. I was told I can upgrade the reciever to anything I wanted. but the 5 speakers, sub, and a reciever for $1100... sounds like a good deal to me. They also had RF-62s and RF-82s for a very decent price (RF-62s was $2499 with a 7.1 Denon reciever).
I guess now with this many options, the job is even harder to decide. I did look at the S-1 and not sure if they would fit in my room that well since the speakers would go in the corner of the room.
