Hello Bill,

Here are a couple of options that you can consider.

The LX Nav S7 and Nano or the LX Eos.

The Eos vario has built in GPS with IGC flight recorder and basic Navigation on a small screen as well as back up battery and built-in Bluetooth to connect to an Android phone running XC Soar, Iphone with Iglide, or Oudie.

The S7 vario and Nano combination give you IGC flight recorder and connectivity to your navigation package of choice as suggested above.

There is a sale on at this point for the S7/Nano packages

Another option is to look for something like a used Cambridge 302 that will be much cheaper and give you many of the same features.
