I wonder how they (DirectBuy) even stay in business?
If you are really looking at replacing home phone service, we opted for Ooma over MJ. We have had it for almost 2 years now and don't have a phone bill (we pay $11 per year for taxes) now and have unlimited calling, voicemail, call waiting, and caller id.
They also offer a premium service for $9/mo that includes a 2nd line, call forwarding and a few other features we don't need. They also offer this for $69/year various times.
Ooma is $199 (Costco) for the "hub" and is an internet based phone service (uses your modem). You don't need to have your computer on for it to work.
We love it.
