we have alot of "low budget" brands of electronics such as Bush or Goodmans in the UK, while they are good deals, the lifespan on them is all ways short, we couldn't afford to splash out on a big tv in the living room so we purchased a Bush 32" model, while it does its job, its developed a blue line through the screen, brown patches and also images burn onto the screen very quickly leaving a temperary ghosting. the tv also lacks features, for example, while it has 1080p hd componant, the hdmi is only 420p, no PIP, and really doesnt offer much more than just a screen.
i've had my Phillips 19" in my bedroom, which i purchased a few months before, and its still in 100% working order. this tv is feature packed, PIP, PC Monitor, 2 1080p HDMI, Digital Tuner etc etc.
So my advice is, if you just want "a screen" that you dont mine replacing a couple of years down the line, buy the cheap TV. But if you want value for money, spend a bit more cash and save money in the future.
