Today (11/21) only, SunRocket is offering 2 years for $199. This “special” seems to come around every other month or so. I’ve been using SunRocket instead of a landline for over a year now now and I remain very satisfied for the price – check out my SunRocket Review for details. My faxing now works 95% of the time.
Added: You can also get two years for $199 from ViaTalk VoIP.
