As a word of advice, don’t settle for a cheap solution. Drawing tablets are EXPENSIVE, but they are 100% worth it. If you buy a cheap tablet, you’ll get cheap quality.
Personally, I use an iPad Air and Apple Pencil 2. You can find things that are similar, if not the same, as refurbished or pre-owned items. This greatly reduces the cost, and will still provide the professional quality an artist wants.
