One Leapfrog system (1 transmitter/1 receiver) runs approx $100 at places like Circuit City here in California, but can usually be found on Ebay for around $59. The picture and sound quality of the system is pretty good. Everyone who has seen my system didn't know they were watching a wireless signal until I told them. If you decide to get a Leapfrog setup don't get the one that sends the signal over your phone lines though, get the one that sends the signal by RF. You can also go to Terk's website at
www.terk.com and look for retailers who carry the systems
