Tazzilla, are you sure selling this is a good idea? Speaking from sad experience, I'm not sure it's a great idea to sell an ED50 (I've done it a number of times, regretted it, and re-bought, so my current model is a keeper). I don't know the Alpen Rainer, but I wonder if anything produced by Alpen can outclass the ED50. Consider a lower-power fixed-mag ep for the ED50, and you may be surprised at the wide, bright and sharp image. Give it a few weeks and compare the two in various lights, and also consider that you may one day want to travel with a scope. Just a thought.
