Jon, I liked my LG Xenon, which I owned up until almost two years ago when I got my iPhone. It had a slide out keyboard. If you think you might use any texting, it makes life much easier on a non-smart phone to have a keyboard.
I'd recommend finding one used via Kijiji or eBay. If you get one that was an AT&T phone, it will work with Consumer Cellular, apparently.
That said - I'd never go back to a "dumb" phone. While I'm not quite as married to my iPhone as a lot of people I know, I find it very handy when I'm out and about - as a GPS, to compare prices or features when buying something, to text my kids, to check my email when away from my computer for long periods etc. I don't tend to use it as a camera for taking serious photos, as I own some superb "real" cameras, but do use it to send quick snaps of things when I'm looking for something for someone, or when I need to record something for posterity (quickly). I find it highly useful - far more so than I anticipated when I first got it.
