Query: if you have a genesis..you need this one!

you need this rf unit for the genesis if you have a hd tv or a monitor..the thing i love about rf units vs the 3 plug cables is that you can string the rf units and connect one system to each other..one after the other...everytime i get a new system(new or classic) i always purchase a rf unit with it..because they are so versitle i have 12 systems back to back with this method..and the picture quality is excellent on all systems...this is a must have for all game systems
