I've been looking into getting a new TV for a few years now, but was a little hesitent due to the high cost. However after my TV died last night at the age of 13 (perfect picture till the end), I would like to find a cheaper TV that can receive the new digital standard. I am looking for a 20" - 27" traditional tube-style television (no LCD, Plasma, etc) that has a built-in digital receiver, and can be had for under $300. I spend most of my days (and nights) working on computers, so I only watch TV for about 2 hours a day, and am generally doing other things during that time as well. Thus, I don't require a large or high-quality TV...just one large enough for my study that can pick up a digital signal without any modifications/additions for the next 5+ years.
I've searched all the major electronics store websites, but most come back with matches for HDTV instead of SDTV or EDTV, suggesting that I misspelled it. The few that recognised the search term suggested a 40''+ plasma. I've noticed that these models are not as easy to find/distinguish as the HDTVs...very few are labeled for what they are. Thus, I'd like to know if anyone can recommend a specific model and/or store where I could get one.
CNET found the RCA 27F524T (built-in ATSC tuner, 480i, 27" 4:3 tube) for less than $300, stating it is the best bargain digital TV available, but didn't state where to get it, and searches for it turned up nothing.
Any ideas?
Thanks,
John
P.S. Talking to someone locally is the same as smashing your head into a brick wall...I recently moved to Sticksville to help bring them up to speed (their internet went down in February, came back up last month)...they have never heard of HDTV, and grabbed a dictionary. (That would be the owner of the largest electronics store within 80 miles.)
