Except $70 isn't really that cheap. It's cheap for a tripod, but it's still $70, y'know? And it was actually the second tripod; the first one was $25 wasted. So, $100 on crappy tripods before....
Anyhow. After 3 weeks of being frustrated by the goofy 3 way knuckle movement at the top, and joint lash causing movement after all the clamps were set, I finally looked through the recommendations here (using search rather than starting a new discussion) and ordered the Manfrotto 055ProXB and the 488RC2. And now I can say, "Oh. Now I understand."
The difference in build quality is substantial. Even as a starter unit, this is absolutely a quality tool, which makes the other tripod seem like a toy.
Thanks for having the information available, POTN contributors!
Word to others: don't waste the first $100; either stick to hand-held, or save for the good tripod. A cheap tripod is the worst of both worlds; more difficult to use than hand-held, and not steady and stable enough to be worth the trouble.
