Our 3-tuner Hopper 2 does switch channels, etc, a bit slower since the "upgrade" to the new software/UI version, but we haven't found it particularly annoying once we found our way around the new layout. The newest 16-tuner Hopper 3 does have a faster processor, just as the Hopper 2 has a faster one than the Hopper 1 which I would not recommend. Either the H2 or H3 will work with your Trav'ler, allowing multiple simultaneous recordings while watching another channel. Additional TV's can be connected using one of the Joey sub-receiver models that communicates with the Hopper. The H2 and H3 models also have built-in Sling streaming capability when Internet connected, allowing you to watch any of your channels or recordings on any Internet connected PC, Android/iOS device, and Amazon FireTV device using a free app. My wife has even watched her favorite soap opera on our coach's bedroom TV and a FireTVstick while we were underway, streaming it from the second Hopper 2 we keep online at our upstate NY vacation cottage.
