I was hoping I could get a photo of mine, but it's bundled in Dad's camera bag (with 350D) and he's had them both for the last few days.
As soon as I get it I'll snap it, but mine is plastic, so is lighter and smaller than JayJaya's. However, it doesn't extend and probably isn't as strong.
I was almost going to buy one like Jayjaya's (as I said earlier, mine ended up being free anyway) but found the head was too loose and the legs were not great when extended with a camera attached. I recommend you try to test if you can in a photo shop, with your camera and lens.
Yes, there may still be some wobble - there is with mine and I will often still use remote/timer to take photos. And yes, you have to think more creatively about where you'll perch it (such as on car roof/pedastal, etc). However, I still really recommend you get one as they're cheap, light (I
always carry mine with me - except when Dad nicks it) and better than trying to be in two places at once/holding your hand incredibly steady for 2 seconds.
I probably sounded very negative before. I didn't mean to be. You should get one, but don't expect miracles, and do test it before you take it and rely on it. And if it isn't strong enough to keep camera + lens at the right angle, consider propping up on something - this is something else to be creative about! I use a book, magazine or camera bag. My Dad uses a box of cigarettes (which is actually better than any of mine, but I don't smoke).
As for the problem of the strap with your current one - it isn't too difficult to sew on a new strap you know! I've done it before!
Even if you do sort out the bag for the big tripod, get a mini one as you will at some point be thankful for having it (it was extremely useful for me in Egypt as I didn't have any other tripod at all). I know without mine, I'd be at least a hundred photos down (if not a few multiples of that)...
Edit: Just remembered, I do have a photo of the thing - it's just not very good. It's from the ferry when we were coming back from snowboarding, my mate was having a play with it to see how it worked:

As I should've said, cheap, tacky, plastic...
