I am currently trying to decide between two televisions to purchase. Both are 27" Toshibas, one being the 27a43 ($279) and the other the 27a33 ($249). the 27a43 says it has a 3 line digital comb filter, the a33 says it has a digital comb filter but does not specify any details other than the fact that its digital. my question is, will there be a noticable difference in picture quality. i plan on using the component inputs for my dvd player. the sound doesnt matter to me, ill be using my Onkyo Ht-s760 for my audio and probably wont even have the television speakers on at all. what im mainly concerned about is picture quality and durability of the set. i dont have the money for a flat screen or hd television and am pretty set on Toshiba because Ive heard theyre the best in non hd televisions. Any help would be appreciated.
