Nikon 70-200 f4 Tripod Collar...

[chrism_scotland]

I just bought the Nikon 70-200 f4 VR to replace a much heavier Sigma 100-300 f4 I was using (never really used over 200mm) it seems like the size and lighter weight will make it a nice zoom to take with me on my travels this year!
I'm looking at getting a tripod collar for it though and the Nikon one is £150 are there any 3rd party alternatives that anyone could recommend?

ive had a couple of generics off ebay that have been good, come for china. Not as good as a proper one, but then not £lol price.
