If you wanna just dip your toes in, get a Celestron, and some aftermarket lenses. I'll have to wait until I'm home to get the specifics for you, but I spent about ~$30~ on the telescope, and maybe about the same on a couple of lenses, and can see Jupiter from my back porch (I live in the country and don't have to worry about light pollution, jsyk)
If you can't wait until I get home, do a search for something like "4 inch Celestron, 2x Barlow lens"
I just went and googled, it was a Celestron Firstscope, which is now around 70USD on Amazon
