Take a look at Clarity by Sagetech and SkyRadar by Radenna. They offer units beginning in the $599 and $699 pricepoint. Looks like the Dual GPS is $799. Nice if your needing a GPS, but the iFly has it's on internal GPS so it's not really needed. We've been working with Sagetech and we have really been impressed with them. They even offer a unit with an internal AHRS.
