I have one and I love it.
I bought it last fall (before it was discontinued), and it has run very well on the skeet field. It doesn't toss empties off all over creation; it dumps them right at your feet. In probably about a couple thousand rounds, I've only had two failures, both were failures to extract and eject, and I think they were ammo related. It handles quickly, carries well, and shoots softly.
Personally, I think Remington could have really done something with it had they pressed on with the design. Instead, they allowed the initial negative press to color the entire concept and didn't bother trying to market it. There were no sporting variants (it would have been great for trap guys), they could also have developed an adjustable gas system to allow lighter loads (according to the manual, 1 1/8 oz. at 1300fps is what you need to cycle it, but mine has cycled 7/8 oz. loads when it was cool out, so there's more room there than you'd think).
People have complained about the reliability (mine's good). I've seen complaints about takedown (not hard, and stripping the bolt is no harder than an AR-15). I've seen complaints about cost (it is priced alongside other new concept semiautos). I've rarely seen people who talk down the CTi II who have actual extended experience with one.
If I found one on a shelf in that price range, I'd be sorely tempted to pick up another just to ensure I had a spare.
