What is a good cordless phone for under $30?

I would recommend the Panasonic KX-TG300.
The sound quality is great, the menu is a bit clumsy and the buttons are a bit too large. Other than that the quality,range is great, very reliable and etc.
The Uniden DCXC40 is also a good affordable phone.
It's a nice compact model, sturdy, and the battery lasts a long time. Overall it's a good product. It's hard to get rid of missed calls from the display and it will not display the date and time until you do so.

Here are some excellent cordless phones for under 30.00 including shipping! These wont break your budget and have some great reviews on them. The 2.4 Ghz phone can be mounted on the wall for easy storage!
