A modem and dialup connection are cheaper and was the standard 20 years ago; Termite TCP and IBrowse worked fine and I still have my original disks. As for the A500 and A2000, I still have AppleTalk networking hardware and software that put them online 20 years ago. But for modern Cerfing, I would get a more modern computer and A1200's are available to US buyers, as are all the other models with the A2000 still able to handle "moderate" Cerfing with a NIC, RTG, and an accelerator.
