I need to pick up an inexpensive tube TV, 20-27" and my only real requirements are good sound (will not be using external speakers) and component video inputs. Last week I grabbed a 27" open box Panasonic from Best Buy but I think I'm returning it. The sound is pretty hollow and tinny and it seems to have a slight geometry problem (my DirecTV channel banner rectangle is more of a trapezoid). Can anyone recommend an inexpensive set (under $300) that meets these 2 criteria? Thanks!
