Which iPaq?

I just traded my iPAQ 3835 in with my CompUSA warranty and I'm getting a $600 gift card! I've got three options:
- Get a 3955 now
- Wait a couple of weeks and get the new $400 one (don't remember which model # it is, the 200-400 mHz one running the new Intel processor
- Wait a couple of weeks, hoping that the price goes down on the older ones and get one of those
Which should I get?
[EDIT]The new iPAQ I was talking about is the 2215, and it comes out on June 16, according to Amazon[/EDIT]
