@Boris_yo the problem isn't so much metal vs plastic, even the plastic ones often don't use plastic connecting bits for the head itself
but they may be wrapped in plastic
the main failure point for a cheap tripod (in my experience from when I was younger anyway) was head failure, ie, eventually the head just wouldn't hold steady
the friction and/or locking surfaces tend to break down if they are cheap
and eventually things just don't hold
if you are using this once a month for a few shots here and there, it should work great
if you are using it 6 hours a day every day, I'd expect one of them to wear out fairly quickly
even with your light weight camera, unless it is just sitting in one place without making adjustments
oh yeah, and if it has extending legs, those are a frequent point of failure as well
but same reason, they are a friction surface
and friction surfaces on cheap tripods don't hold up well over time
I actually know someone who had the sunpack one
but if you need light duty and don't mind if it doesn't stop exactly where you set it, then they should be fine, just don't be surprised when they also wear out
a $30 tripod isn't something you generally use for 10 years.
they'll need fairly regular replacement (which can still potentially be cheaper than using a better tripod, but factor in the fact that the more expensive tripods do last longer as part of your decision)
