I was leaning toward IPS because of the better viewing angles to be honest.
The LG looks like a good choice at the current price of around £120
Colour should really be the buying point with IPS' TBH. So much more vibrant. I find with TN panels. Youre sitting down in a stationary place, so getting the TN panels to face you isnt a big problem.
I never undertood why people care about viewing angles FOR a triple monitor setup :S
