I had good luck there for our phones for many years. J loved her Motorola Razr flip phones, and I used a Palm (something or other) for many years.

The Razrs would usually fail due to the flexible cable dying. And their battery life is crap these days, so I wouldn't recommend them now (even though it's hard to beat the form factor).

Maybe something like this LG A340? $50. Amazon reviews.

But seriously consider a smart phone if you can. Most of the price of a phone is in the plan. You can (or used to be able to) get a $30/month T-Mobile plan with 5 GB data, 100 min of calling and free texts. It is a month-to-month pre-paid plan, so there's no long-term contract. If you get good service from them in your area, and don't need a huge amount of calls, it's a good deal. T-Mobile will let you pay for a new phone over 2 years, also too. Battery life will usually be much better with a newer phone, also too too.

HTH. Good luck!

Cheers,
Scott.
