I'd definately get the monitor from Onvia.com. They have free shipping. Unfortunately, someone told me the pointclick and $25 off deal is gone but they still have very cheap prices and again free shipping is important for a big heavy monitor.
I was gonna recommend the Hitachi CM615 or the Viewsonic E771 but you already have those narrowed down. I couldn't tell ya which is better but a lot of the people say E771 one is good. However, the Hitachi CM615 has a substantially lower dot pitch (.23mm compared to .27mm of the E771) but I don't know how much that matters. I think you would be great with either one. You could check the refresh rates on each from the manufacturer but I believe the E771 ones are higher.
