Two major considerations for DSL are the upstream and downstream speeds. The different types of DSL connections all have different speeds. Some types are symmetric, both upstream and downstream speeds are the same, and some asymmetric with the downstream being faster than the upstream in most cases. Many groups are offering free setup or other offers to encourage sign up. Ask for the details of what is covered and what is not in a bottom line price.
Some providers allow self-installation of the software and hardware as a lower cost alternative.
You may also have options to buy or lease hardware from the company or to purchase a compatible product. Pitfalls Keep in mind that you could be dealing with the phone company in addition to your DSL provider. The phone company owns and takes care of the physical lines, and other companies can lease the line from them. This setup can mean that while sign up is with one company to install the hardware, the phone company completes the line installation before your service can begin. Your comments, suggestions and criticisms are welcome.
