hi all - anyone here have experience with ir repeaters? i saw some on this website that seemed to be a good deal. http://www.iautomate.com/infrared.html question is i thought ir repeater setups were really expensive, like several hundred dollars. this website makes me believe i could do it for just a couple hundred. another issue is that it appears to only let me do four components...i have quite a few more then that. anyway, just wondering if anyone here has done it or has any comments. thx!
