Hi, John,
I've been traveling and typically can't reply to PM's by Blackberry.
Suggest you do the best research you can under the circumstances (online, local dealers) and make your decision based on that.
Don't suffer from analysis paralysis, and remember, no matter what you do, someone at some point later after you buy will offer a better one for less, but if you don't buy, you won't find anything like it ever again.
Not always true, but true often enough that when I am trying to make a decision, I just do reasonable research, make my decision, and then just enjoy!
