This is the one I'm looking at.I'm trying to get them to go down on the price.That's what I had when I bought my Nitro. Then I upgraded to the RBZ, used that for about 4 months. Then I just got the RHB and love it.
You can get the RBZ cheaper than $500. I paid less for my RHB than my RBZ. I would do what I did. What ever RBZ you buy try to get one around the production date of your Nitro. It's just that it will have the latest software.
Is what you brought Ver.4 or Ver.5.Items showed up today.
