This is a good question. Your first decision is whether a table saw or sliding miter is best, considering they're quite different. If you're working on small projects around the house, a sliding miter saw is all you need. It can handle cross-cuts of boards a few inches wide, and gives you the flexibility of being able to deliver angled cuts, too. A table saw, on the other hand, is designed for bigger projects like cabinet-making. If your plans include built-ins or toy boxes or larger shelving, a table saw is best suited for you.
Based on budget, you won't find many choices for a table saw. For a sliding miter saw, there's fortunately quite a good selection of tools under $200. My gut tells me a sliding miter is what you're after, and in that case, I'd research the most current models and check out reviews online. You can see a wide selection at a store like Home Depot.
That said, for greater durability you need to spend more money, so if you plan to use your sliding miter saw every day, save up for a brand like DeWalt or Ridgid or Milwaukee. Assuming your jobs are more occasional, though, Ryobi has a nice sliding miter saw with a laser guide for less than $200.
