My first router was a Crafstman fixed base, which I bought so that I could put a groove in the edge of 3/4" plywood to accept plastic T molding. I was building computer table kits for resale at the time. Soon I found that I needed the features of a plunge router, so I bought a DeWalt plunge router, a good all around performer, which I reccomend. When I aquired a router table, I bought a Harbor Freight 3 hp plunge router. Not very satisfactory. Although it seemed to be a bargain, I soon discovered that there was a slight wobble to the shaft, and fine work was impossible. I replaced that with a Freud, which is wonderful.
[At one point I ordered a small trim router from Harbor Freight but they had cut so many corners with it that it was practically useless. I sent it back, no problems with refund].
My advice is to decide the purpose for which you will use your router and buy a suitable one of a major brand. There are plenty of router reviews available out there to help you decide.
If you are like most of us, you will eventually end up with more than one router anyway.
