Unfortunately the the focus has gradually been getting worse for the last few years; it's no longer quite as sharp in the corners as it was a decade ago when I bought it. It may only last another four or five years. Otherwise it's great.
It's flanked by a pair of 23" ViewSonic IPS LCDs @ 1920x1080. I don't use them for programming as much as I'd like, but I do generally use at least one of them to test what I'm writing.
A single IPS 27" 2560x1440 is great, though. (I used one for about a year) Tiling 3 windows vertically is wonderful, but it sometimes feels too big. Multiple monitors never worked for me unless they're small (<19")
At home I have three Acer S231HLs (23"). They're definitely not the best monitors, but they can put things on screen, which is the most important thing to me.
At work I've got a 24" 1920x1200 HP S-IPS (forget the model, $400ish MSRP), and some random 19" Viewsonic I requisitioned from somewhere. The HP is really great, if you don't mind the only inputs are digital only.
