Panasonic phones sound the best, but they generally start to have keypad problems after 2-3 years. I'm on my 4th one now - Keep buying them because the sound quality is great, but I'm getting tired of the numbers slowly dying on me.
My junky V-tech cost a third of the price, sounds nearly as good, and has been through hell and back and is still as good as new. Your mileage might vary.
