It's best if you look through the buying guide first. These are recommendations for tablets that have have screens. If you are looking for a tablet without a screen go here: pen tablet recommendations. If you want a standalone tablet, go here: Standalone drawing tablet recommendations.
Make sure you know about anti-glare sparkle before you buy a pen tablet
Please keep in mind that pen displays are not inherently better than pen tablets that don't have a screen. More here: pen tablets vs pen displays
