If all you use is Calendar, contacts, memos etc then you don't need a really fancy phone with a data plan. The data plan is just for internet and email kilobyte usage. Even phones a step down from smart phones (smart phones = blackberries, iphones, palm phones, android phones) will have calendar, contacts, memos etc.
Being stuck in a contract for another 18 months makes things a lot more difficult, but I bet if you go down there and tell them you don't need to use any internet or data services and just want a single device to use as a phone that will also be easy to input calendar, contacts etc, they will have something for you. Lots of people are in your same boat.
As for my ZJ, my current ZJ is a 98, but I've had a 93 and 2 95's over the years. NAGCA is not a local club, but there are a lot of local ZJ/WJ guys here that are members of NAGCA. I'm hoping to put up some regional forums on NAGCA shortly to help people find other local grand owners.
