One-man rigging aids - is the electric up/down control worth it?

I build a homemade one based roughly on UDO's designs back when I had an HP-14. I nearly lost all my glider friends at wave camp asking for help rigging! We used an electric actuator that made use of the remote control unit from a $40 Harbor Freight winch and a small 12V LIPO battery. The system was a bit heavy, but was very helpful when you don't have a ship where everything doesn't line up perfectly every time. I think we spent a little under $500 total in parts. happy to share photos if interested
