Pretty hard on that guy, Channel Vision does make baseband video amplifiers, just not that many of them. I could swear they made an S-Video amp/splitter as well, but I can't seem to run it down at the moment. If its just a little bit of boost, I've had some success with the old Radio Shack A/V amplified splitter, the new model is 15-1172 (they've added S-Video), but if you are looking for the real deal Pelco EA2010, (adjustable gain and equalization).
