Last week I bought a Samsung 913N on impulse(it was the only decent one the store had in stock and it was on midsummer eve so I couldn't exactly take my business elsewhere) - I think it's in the same series of analog LCD monitors and the drivers keeps the 710N in the same tab as the one I bought(other models are listed separately), so they might resemble each other, except the one I bought has a 8ms response time that's probably the biggest differense.
Anyway, I was a bit worried at first when I found out it had an analog connector(and was 19'' big), but it wasn't a big deal considering that I just use it at home, it works very well as a display for casual use(games, web, media, code).
I'm happy with it and nothing has bothered me yet, it works well and I can't complain about the picture considering the price and the effort spent on selecting and buying it.
So if the 710N is similiar to the one I bought I'm pretty confident that you wouldn't feel like a fool if you bought it. People worry too much about their LCD/TFT purchases, they get some kind of feature-vertigo from all the variables or something.
Sidenote:
I work in graphics/print so I would like to belive that I can give some decent input on the image quality
