'm new here and seeking some advice...

The only 2 lenses I have yet are slow ones, so camera shake is a real issue for me right now, thus I use tripods a lot. I stop using my bean bags a while. For now, I like doing landscape photos but find it annoying to have to set up for every little potential shot when I'm out driving around.

I see they have car window mount tripods which would make things far quicker and easier if they are actually convenient or not in actual use?
The ones I've seen online look pretty cheaply made and may not handle a heavier SLR?

Anybody else done anything like this?

Thanx.
