I think I need a UPS? If so, which one?

When the heater in my place (convector) cycles off, my TV goes black for a second or two. I worry a lot about what this is doing to all of the electronics using outlets in the same wall as the convector. Do you think I need a UPS, and can you guide me through the process? Details inside!

PSU question

Electronics filter: What can I do to make a 24v PSU turn into a 18-19v PSU? It's 0.5A power supply which as far as I can tell is important to know when using, say a resistor to lower voltage. But how resistant should the resistor be? I've found information on how to tell a resistor's value, but not how it will actually effect a line's voltage or how to calculate it. Are there any good sites with this information? Also what will happen to the amount of amps the PSU supplies when I do change it to 18/19v?? Also, what can be done to increase the amperage of a power supply? What inside the circutry is actually dictating the amperage?
