I bought a used HP Elitebook on eBay for a similar purpose. I can browse and do video calls on a bigger screen when the fancy strikes. Pretty much any used business laptop should work. I think I paid about $300 for mine and I paid extra for particular hardware I thought was neat but you don’t have to. Only thing to keep in mind is the battery will likely be pretty worn.
