Remote Shutter/Wireless Release

[Nicalum]

Does anybody have firsthand experience with a Remote Shutter/Wireless Release?
Which one of the remotes below is the best for a Nikon D300 camera?

Opteka RFT-40 Remote Shutter Release & Wireless
PISEN™ Remote Control Shutter Release Switch
Yungnuo Wireless Shutter Release YN-126
Yungnuo Wireless Shutter Release YN-128

Thanks in advance.
