I'm looking for a cheap monitor. I was thinking of getting a 17-19 inch CRT on Craigslist, but there are some LCDs that aren't too expensive, usually about $50 for a 17". If I get an LCD that's a few years old, will it be decent compared to current ones? LCDs are relatively new, so I'm wondering if they rapidly become obsolete and inferior, like other things in computing. For instance, I see a Samsung 710N for $50, which hit the market 4 years ago. They now sell the 740N which seems to have almost identical specs, for $200 new. Both have good reviews. Would it be a wise choice? It's just for general personal computing. I've looked at new LCDs in stores and they almost all look nice, but the Dell ones in the public library (don't know what model or how old they are) don't look as good as my Emac CRT. I'm wondering if I can get something close to what's in stores now.
