I have a Karavision which I bought last year (around 7.6k ata). Looks-wise, the Hyundai comes out on top, and mas mukhang heavy duty. One bad thing about the Karavision is that wala syang component out (composite lang & S-Video), but since I have an HTIB, ok lang.
Go for LG or Hyundai. The Karavision looks cheap kasi, and I just bought it for the Karaoke experience, hehehe
