Now its from a place called the good guys (these are sale price) - but they offer pay less for cash so i should be able to get them to reduce the price a tad more aswell.

Now in terms of value i think it would be the LG 32"er? Correct? higher numbers the better? lol - dont know the tech specs and what they mean so sorry bout that :*(

Is the 42"er LG a good one to grab? comparing the prices etc to the rest of them?

Thx guys!
