I really good pair of boots is going to be expensive, so be ready to spend at least $100, likely a bit more. Carolina and Red Wing are two of the top brands, the Timberland Pro line is decent and Carhartt boots are really good as well (they are made by Red Wing).
I have had a pair of Carhartt 8" er Lineman boots for a few years now and have been very happy with them. The only thing I've had to do since buying them is replace the laces which is to be expected. The boot itself is tough as nails. They are supportive, have great tread, are durable as hell, and they will keep me dry all day when I'm mowing and landscaping in the rain (I can't say the same for other boots I've owned). At the end of the day you have to go with what fits and feels good and meets your needs, but those brands are a good place to start.
One last thing to keep in mind, if you are buying a burlier boot that is mostly or all leather, it's going to have some break in time. The first week or so that I owned my Carhartt's was not fun. I had chaffing, some small blisters and just general discomfort. However, since they got broken in they have felt great. And I feel like I could kick in a concrete wall when I'm wearing them.
