Eh, I live on the edge. Mine is a cheapo. I don't even know what the brand name is off the top of my head.
I've used it maybe 3 times in the 3.5 years I've been shooting, and when I use it, I'm never more than 6 inches from it. ::shrugs::
I totally get the benefits of getting a quality one, but right now, for as little as I use one, I'd rather put that money towards new glass, a new modifier, lights, etc. I'd sooner buy a monopod than a tripod as that would be more useful to me for what I do, but even then, that's really low on the list right now.
