This article is from the Amiga Networking FAQ, by Richard Norman with numerous contributions by others.
Shopping for the right level of WAN connectivity can be difficult.
Shell accounts are the cheapest, but may not offer all the access you want. SLIP and PPP offer full two way communication, but at a slightly higher cost than shell accounts. Commercial accounts, such as AOL, may incur extra phone charges or put limits on your internet access, but do usually offer additional services not found on the internet. Direct connections can be fast, and with a full time direct connection you can host your own web sites and offer services. The down side to direct connection is that it is expensive.
You have to run the cost comparisons yourself to see what level of access is right for you.
Books on the subject:
O'Reilly & Associates, Inc publishes book that offers some good ideas for doing cost comparisons. It is called "Connecting To The INTERNET" an O'Reilly Buyer's Guide.
Another book to look for is "Connect your Amiga!" by Dale Larson of IAM .
I'm sure there are other books as well. Time to head to the bookstore ;-)
