There are 3 desirable attributes that determine the quality of a tripod
Lightweight
Stable
inexpensive
In practice you can only pick two at at time. For example, if you want a very lightweight and very stable tripod it will not be inexpensive. You can get inexpensive and stable but it's going to weigh a ton. That might be okay depending on whether or not you plan on traveling with it and how you shoot.
I do primarily landscape work so nearly every shot that I take is from a tripod. My setup cost me ~$1200. While that's probably overkill for your needs its important to understand that this is one of those situations where it's cheaper to buy "the right one" first rather than buying several cheaper ones that don't do the job and then have to buy the right one.
Things to look for.
You want one that you an look through, standing up, without extending the center column. An inch or two isn't a big deal but if you've got to fully extend the column it's not going to be stable.
The fewer the number of joints in the legs, the better. That does extend the collapsed length so you have to decide which is more important.
A ball head is easier to use than a "pan and tilt" head.
