I recommend the Dell 1703FP for office use. I received two of them recently and they are fabulous, esp. for the price. I originally wanted the EIZO L568, then I ordered two Samsung 172x from a "reputable" vendor which will remain nameless because of the ridiculous situation I had to incur with them.
Long story short, I went with Dell. I ordered online, the items were received 3 days later, no frills. Net cost for me was about $370 per monitor. If you have a small business account with them and you are ordering bulk, I am pretty sure you can negotiate the price down by calling Dell direct, so in terms of cost, warranty, return policy, and quality relative to what you are paying, I really feel Dell (esp. for a business) is the way to go.
In terms of quality, the 1703FP is pretty good (7.5/10 personal scale). The quality on DVI is noticeably different than analog but both are pretty good (comparing to NEC 1550x, Samsung 710T, Samsung 173P). Also, the 1703FP has a thin bezel, which was a requirement for me. Width is about 11mm and Height is about 13mm.
Anyway, Dell has a really good return policy and very competitive prices and I think for a business, this is much more critcal than the typical responses you might get from this forum, as it is a gaming site (get 12ms, etc.). Of course this is only my opinion though.
Im using the basic dell 17" fp's here at work in a dual monitor setup. They work great but you MUST run them at their native resolution of 12x10 or they look foggy; as with any flat pannel.
