Chris I have a tripod QR plate on my Ds with the same sort of anti-rotating lug on it, it hasn't caused any noticeable damage.
Not sure I could fit that handgrip and my QR plate though

I have been tempted by the Op/Tech version but haven't yet succumbed. It uses the same system as their neck straps.

I don't know the Tamrac 3571, and couldn't find it on their website so I can't comment on it. However I have the Tamrac expedition 5 backpack. I use it when I take the Bigma out ( which doesn't fit in a Slingshot) and find it comfortable to wear though it is heavy even without the gear in it. I also use it as hand baggage when flying.
For other trips I take either my old Lowepro Nova 3, or even just a bumbag that holds the camera and a couple of lenses.
If you don't have a lens the size of the Bigma then I would go with the slingshot too, or look at messenger type bags such as those from Crumpler. I see that Tamrac now also have a sling bag, but without the extra compartment the Slingshot offers. Pentax also do a Slingshot type bag.
The ultimate carrying bag is probably a Billingham - they don't look like camera bags but hold stacks, and have a price tag to match.

I have to agree with John - this photo would sell and sell, poster, postcard whatever. Find a publisher quick - make your first(?) million on the strength of your stroppy kitten

The grip is part of the special package I believe. http://tinyurl.com/2twr75

Damfino I apoligise to you.

Sorry, but is this poster serious? Why as a first camera, let alone a first SLR would you choose the K10D and then expect it to behave like a P&S? Yes the K10D is a superb camera, but it is not a beginners camera. Surely if you are spending a great wodge of money on a camera you do some research first into what you want/need and how to use it? And understad the differece between a P&S and a dSLR.
Or am I the stupid one here? This has the feel of a Troll to me.

I like the colours in the second one. The first one reminds me of Sunday morning walks working up an appetite for the roast.

Doh! He's only painted on, so he won't be around much longer.
What is really funny is the pagans getting upset about it - whilst the Giant is not an ancient figure at all but a joke against Cromwell.

I like the photos though ChrisA - did you have to fight your way through the crowds to take it?

Lilly that sounds an exciting trip - where are you going?
