I have bought some of the smaller Insignias from Best Buy that have worked out pretty well. I know at one time some of them used a power brick so they run off 12 volt. I think this one might work, 20" Insignia. If you can go to a Best Buy, look at the back of the set and you will be able to see if it has 12v input. There is also a larger 24" but I don't think it has the 12v input, 24" Insignia.
If you keep an eye out you can usually catch them on sale. Have seen them occasionally as their deal of the day.
