I found myself doing the same search about 10 years ago when my favorite CD burning software disappeared.
After some Googling, I discovered a PC magazine article that mentioned Ashampoo Burning Studio as one of their recommended programs for CD/DVD burning and copying.
I had never heard of Ashampoo (it's a German Windows software company)
I've been using it for the past ten years and it works very well for burning and CD/DVD copying.
It's $29 and you can find it here:

Good luck
