I currently have a Pronto NEO (TSU500) and I'm getting a bit frustrated with the small screen not being able to hold all the buttons I'd like to keep things simple. I was just about the pull the trigger on a TSU3000 when I realized they now have a TSU3500 available. The TSU3000 can be found for a really good price on the net, but apparently, the TSU3500 is not available on the net and where you can find it, it's almost twice as much as you can get a 3000 for.

My question, is the TSU3500 much better than the TSU3000? I see they have improved some features and capabilities but are the improvements worth it? Should I hold out for the pricing on the TSU3500 to come down (and maybe start showing up on the Web more), or would I probably be just as happy with the TSU3000?

Thanks,
Ray
