Radio Shack also sells a 4-way A/V Distribution Amplifier box that takes RCA or S-Video in and allows you to split out to several TVs using RCA or S-Video. (This is for someone who does not need to split out to a TV using coaxial.) I use this amplifier box and really like it. See the following website for information:

Also, in order to have less stress on the plug-ins of the unit, I buy small adapters that I leave in each slot I am using and plug my RCA cable in and out of those each time. This saves on the wear and tear of unit if you were to pull the plugs in and out of the unit every time. I also leave one of these adapters in the plug-in on my TV to save wear on that too. See the following website for the adapters I use:

I prefer sticking with RCA myself and have only used coaxial a couple times when I had to use an old bar TV that only took coaxial. An RF Modulator would need to be used then.
Hope this helps some. I would love to hear others ideas on all of this.
