I have all Monoprice cables on my system and they work fantastic. I have an in-wall rated 25foot HDMI cable and the only negative (if you can call it one) is that the ends of the cable are HUGE!

My plasma is an on-wall install and the cable forced the TV a good 5 inches away.. the solution was buying a 90 degree HDMI male to female connector also from monoprice which allowed me to drop the cable down along the back of the instead of straight back.
