I know the 20 is OTA capable whereas the 23 is not, but does the 23 have any superior capabilities over the 20 such as better features, better picture quality, etc. If it did I could always purchase an AM21 to do handle the OTA thing. There are still some 20s available for purchase at various places on the internet. Isn't the 23 the receiver D* sends you now when you purchase an upgrade receiver?
