I'll second Glen's thoughts, get a good tent. Without a good night's sleep backpacking is just an elaborate form of masochism. A good tent will keep you dry in almost all sorts of weather. A "price point" tent typically includes manufacturing short-cuts that both cut costs and reduce utility. You get what you pay for.
I have been using the same Big Agnes Fly Creek (2 lb) tent ($350) for nearly nine years now and I have never gotten wet while using it. It replaced a Sierra Designs Light Year ($200, 3 lb) that seldom kept me completely dry. The Fly Creek cost nearly twice what the Lightyear did but over nine years the cost difference was small compared with the difference in performance. Don't be penny wise and pound foolish😂
