I bought a few accessories for my FZ200 and I'd like to share the experince with all DP users.
1 - Spare batteries. Two months ago I bought 2 aditional batteries from E-BAY. They work perfectly.
2 - Strap. Bought a shoulder strap. I don't feel the waight of the camera, it's comfortable and it's possible to mount the camera on a tripod, with the strap attached.
3 - Cheap CPL. Don't buy this one. IQ is not usable on more than 9mm of focal lengh.
