I looked at the Google Maps API for adding a simple map display to my web application. Since it's a commercial app I'd need the Premier API which starts at $10,000 per year. Waaaay out of reach for me right now. Does anyone know of a good, affordable alternative? It would be fairly low-volume geocoding from addresses, movable/zoomable map display and maybe some distance/area calculations in the future. I'd rather not need to maintain my own geodatabase and the API must support SSL.
