Get the Rode NT1 package and a Hercules mic stand:
A music stand to put your reading material on is also a good idea.
Why the Rode? It’s a high quality mic for the price and will last you years. You won’t need to upgrade for a long while. You’ll also be competing against artists with really high end equipment and treated spaces so you want to get the best bang for your buck.
Why this mic stand? It has a hand latch for easy adjustment in seconds. You can use it sitting or standing.
Why a music stand? You don’t want your mic to be in front of your computer while you read off the screen. The sound bounces off the screen and gives a hollow echo-y sound to your audio. also electronics will raise your noise floor the closer your mic is to them. Music stand let’s you move further away from your electronic equipment.
Do you absolutely need to do this. No. But I can always hear when a narrator is using equipment too close to their mic. The layman might not hear it, but I always recommend aiming for the highest standards possible within your budget, not the lowest.
