Good budget circular saw recommendations

Getting ready to buy my first circular saw and was hoping to get advice from people who probably use these things on the reg. I’m buying it to shave down fence posts soon, but I’m sure I’ll need it for other projects in the future. The budget I’m setting is $100, but I’d like to spend less. I’m actually willing to spend a little more if the features are important enough to spend the money on. I realize this isn’t going to afford a top of the line saw with all the bells and whistles though. Just hoping someone could point me in the direction of a saw with good enough price to performance, and I would also like to hear about things you like about your saw and if it’s worth the money. Like does having a cordless saw matter enough to you? Should I care about buying one with a laser guide? What qualities about the blades should I care about? Are there brands you really liked or brands I should make sure to avoid? I’m sure these are questions with some obvious answers; I appreciate any help thrown my way regardless.
