Wow, that's quite a deal on the Sony 23"...
I went for the refurb Apple 20" for 1099. delivered, from MacConnection. Looks perfect, and I do appreciate it's creature comforts, like the system on/off/sleep from the monitor, via touchless photo sensor, even.
Had I first seen your post about the Sony though, I might have been tempted to stretch the credit card even further...
