I bought a couple of cheapo ones figuring it was just for the RV. Each and every one died for one reason or another mostly the sound and/or cable connection circuit boards go out. I did break down and took the one where the antenna connection board went out to a TV repair shop they replaced it for 60 bucks. Said they see a ton of the cheapo no names come in for that reason.
I finally went out and found a 'small' Vizio flat screen. WHAT a difference! How many channels you can get when camping with the antenna DOES make a difference from brand to brand. The Vizio pulls in about 10 more channels then any of the cheapo brand ones do.
