If you're just trying to get some starting strength and then going to the gym, just a get a cheap set of dumbbells between 15 and 30lbs each depending on your strength. You could also buy used to save a few bucks. Rusty ones go for cheaper and you can usually get all the rust off the handles with some WD40 and a wire brush. Could also go for adjustable dumbbells if you want a more long term investment
