Yeah, and I just bought a WAAS GPS from Amazon
https://www.amazon.com/Dual-Electronics-XGPS150A-Multipurpose-Augmentation/dp/B006M49G80/ref=sr_1_3?s=electronics&ie=UTF8&qid=1525361200&sr =1-3&keywords=waas+gps
for $78.58.Â* I can use that to provide a good signal to my iPad if I
choose to use it in my glider for powered repositioning flights and
using Garmin Pilot software.

Seems to me that the price of a "suitable" GPS source has more to do
with paperwork (TSO) than with technology.
