I won't say what is best, but i fix 'em all, and RCA is SUCK!
Seriously, they are junk.
Stay away from them.
I would rather have a Sanyo.
Panasonic, Toshiba, Sony, JVC are all good.
JVC is most expensive to repair.
SONY is expensive too.
Panasonic makes a good set.
I personally don't like toshiba, but they are supposed to be good sets, and I don't see many(if any) for repairs that aren't many years old.
