I have the CS4. I love it. I drove to Atlanta from Athens to get one from REI. They were out. On the way home, the wife insisted on stopping at the local megamall. Halfheartened, I agreed thinking that Galyans MIGHT have one. NOPE! While she was in Yankee Candle, I strolled up to Sharper Image. I begrudgingly eased in (I hate malls and mall stores). There in a glass case was the CS4 and the S2. "Just got the floor model left on the CS4, the S2 is already spoken for" the teenage employee responded. Noticing the $79 price tag (ouch!), I asked "any discount for it?" " Yeh, display models are half price" (sounds good; locked in glass, it had remained scratchless) "I'll take it!" At the register he informs me that there is one left so he can't give me the discount. " I'll take two!" Now I have one and my wife has one for a total cost of $120!
