A few people have recommended Radio Shack's little pyramid remote extenders. Are they any good? Other suggestions under $50? My office neighbors the living room and i want to keep my equiptment rack in my office and just the TV and spkrs in the living room (wife's wishes). I need something to operate through one wall, same level in the house. What's my best option? Also, what about speaker wire, S-Video wire, and subwoofer cable - if i need to run 20 or 30' or more even, is there a major loss of quality? Brand recommendations for longer runs, or do they all degrade over length evenly? Thanks!!!
