if you are looking for quality, then you should grab a Samsung, Sony, or Sharp Aquos.
However, be ready to pay a bit more for these brands.
The sharp Aquos will probably be the cheapest reliable brand tv you may find.
As far as Toshiba/Mitsubishi (not sure which one was) goes, i heard they were beginning to be good but just to be on the safe side, go with the ones i told you up there.
A 19inch or 22inch will definitely cost you around..300 dollars. (Note: i bought my for 1000 a 46inch samsung. i was not in the market for a small hdtv so i wouldnt know the price. sorry)
so start searching for these brands and see what you can get. You may actually go for a 26 or a 32 by adding a few 50 dollars depending on the price. compare and contrast them
As i said, you can go with brand-quality name or the other cheap type of hdtv like vizio and sylvannia, etc.
Make sure is 720p. you can notice the difference of 1080p on 46inches and above. most brands out there tend to give you 1080p for these small tv but there is really no difference on the small screen but you will be paying more.
So yes, go young grasshopper!
