I have a 2nd generation, which has the home button. (I got my wife the 1st generation when it was first introduced and it’s still functioning. The battery doesn’t charge well but it’s still good for surfing the web and playing games.) Apple changed the pencil. I wouldn’t get any iPad that wouldn’t support the new pencil, which I think is from the 3rd generation when the removed the home button and introduced rounded corners. The old pencil has a lightning connector and plugs into the iPad to charge. The new pencil magnetically attaches to the iPad and charges. Apple should release the next generation soon. (Maybe in a couple weeks.) Hopefully you can get a used one at a good rate when that happens.
