I agree this really sounds like a tripod problem.
Here's a story I love to tell... I have a friend who bought a budget tripod. Funds were tight. He didn't want to spend any more than he had to spend... so he bought something minimal. His first tripod broke. So instead of buying a better tripod, he bought another cheap tripod. While shooting one his young nephews playing, the nephew managed to kick one of the legs and that tripod broke (he was surprised it broke, he said mostly his nephew accidentally tripped on the leg, it wasn't much of a kick). So he bought *another* cheap tripod.
I think he was spending something like $79 on the tripods (we'll call it $80)... but three tripods later and now he's up to $240. So when you consider that he's now basically spent $240 on an $80 tripod... buying a better tripod from the start doesn't sound like such a bad idea.
This is the difference between "cheap" and "frugal". The cheap person wants to spend as little as they can "right now". The frugal person wants to spend as little as they can ... but over their entire life. That means they'll spend the extra dollar for dependability if they think it means they'll have never have to buy it again.
A tripod should be durable enough to last a lifetime. If you're on a budget... don't be "cheap", be "frugal".
Better quality tripods allow you to detach the head from the base. You can think of it as a leg assembly that comes up to what I think of as a "shoulder assembly" (that's not it's official name... it's the point where all the legs attach at the top and it usually has a center column. The top of the center column/post has a plate with a 3/8" 16 TPI stud (that size is an industry standard). You can attach whatever "head" you want on that "shoulder". Most photographers get a ball-head.
Most decent heads have a quick-release plate. I actually prefer the acra-swiss type dovetail rail and saddle. This is because you can get these rails in different lengths and that means you can slide the camera's rail forward or backward along the saddle and clamp it in a spot where it's balanced (so now you don't have weight trying to make it sag). While Arca-Swiss is a brand name... the dovetail type rail that they use has become something of an industry standard. So you can find LOTS of tripod manufacturers who make heads that use the arca-swiss style mounting saddle.
