If you are currently a cable/DSL subscriber, you might currently be leasing/renting your equipment from your provider for a monthly charge. If this is the case, why not just buy one?
One thing providers do not want you to know is you can buy both DSL and cable modems relatively cheap. You may hear the “we won’t support it” or “if we change our signal it won’t work” excuse, but for the most part, this is non-sense.
Here are some of Newegg’s listings:
If you are paying $5 a month or more, these modems will pay for themselves in about a year, so in the long run you can save quite a bit.
If anyone has done this, please post the modem you use and your ISP to help others out.
