So, is anyone playing with the Move or the Sharpshooter?
 
I got the Sharpshooter yesterday and haven't had too much time to use it, but it is pretty fun. It was difficult getting used to the controls, but it feels pretty good. It is somewhat awkward holding it sitting down but not really  uncomfortable. Good accuracy though I'm not sure how much the game itself is helping you with that. Tons of customization for the sensitivity for it as well through Killzone so that is nice and I will have to play around with it. 
 
Overall, I say it will probably end up being worth the $100 I spent on everything (I got things on sale and with discounts, probably more likely to be $150 at regular prices). Anyone else using this?

I'm using just the PSMove and the nav controller and I think it works pretty well. I was going to get a sharpshooter but I canceled it.

It looked interesting but not enough to justify dropping that much cash to just play some games in a *unique* way. 

The Move is definitely worth it.  Superior to the gamepad in all ways save turning, but you get used to that and the accuracy you gain outweighs the drawback.

I found that playing with a move controller and dualshock 3 worked fine.  While it is the cheapest move related option to play Killzone 3, I still felt it was better than playing with just the dualshock.

" It must be me then.  I found Move almost unplayable with KZ3. I am a klutz though. "

I've beaten the campaign with the dualshock and I was going to wait to pick up a navigation controller since holding the dualshock one handed feels awkward. I really liked the precision I was getting with the Move.

I vastly prefer the Move+Nav combo to the Dualshock 3 for this game. Once you get used to it, which for me took about three hours, you become crazy accurate. It feels like it adds a bit of immersion to the game and the controls require less thinking since you basically use three or four buttons. It's more...natural. Keep in mind that even if it was the best control scheme ever devised, it's still an entirely new controller at first. As keef mentioned above, it will be like the first time you switch to mouse and keyboard or maybe from D-pad to analog stick a decade ago. But it's a LOT better. I wish every shooter used the Move this way. I haven't tried the Sharpshooter yet but that's mostly because I can convince myself to buy an accessory that costs more than Red Dead Redemption until I at least have that game. I hear good things about it from friends, though.
