Wheelchair cover or canopy

Does anyone here use a cover or canopy over your wheelchair? My electronic wheelchair is an expensive and delicate piece of equipment. Texas weather is notorious for turning on a dime. It would be very distressing to go 3/4 of a mile to the grocery store in good weather, but then be trapped there because of unexpected rain. I see this very expensive solution,... $700. I can’t afford that, and I don’t think it would fit right on my Quantum anyway.

Or this. Also expensive.
