It looks like my epich monitor search saga is coming to an end with the purchase of a 21" Sony Multiscan E-530.
There's not a lot of information about it on the internet, but I feel like I can't go wrong for 30.
That's about 1 per kg, though. Moving that beast around is going to make for an interesting warmup.
Edit: The thing I REALLY love about this monitor is that unlike Dell and LaCie's, the bezel is 100% square and smooth, so I won't have to decase it when I build my arcade cabinet nor I'll have to move around the board with all the video controls.
