which of these 2 17" tft's are better?

http://www.aria.co.uk/specials.asp#2116

both on the same page - 17" arianet 12ms monitor or dell 17" monitor?

Looking for it as a second monitor to use in addition to my 21" trinitron CRT.

also, in your experience, is 17" too big for a second monitor or should I go for a 15".

17" is ideal, 15" was good a couple of years ago and it's still ok, but 17" is the better bang for buck and it is also the size that led the response time drops over the past 2 years.

I have had both Aria (Digimate) and Dell 17" TFT's and I would go for the Dell.

There is a little in it spec wise but the Dell is the more solid screen quality wise and I kept the Dell and sold the Digimate. Both are ok for games, the Digimate is also overly bright IMHO and that of 8-10 friends that bought them cheap ;).

I have the dell and its great, well built as DJWillis says

go for the dell.
